Accounting Policies [Abstract]
Basis of Presentation	1. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission, or the SEC, and U.S. generally accepted accounting principles, or U.S. GAAP. Certain information or footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to SEC rules and regulations. In our opinion, the financial statements include all adjustments, which are of a normal and recurring nature and necessary for the fair presentation of the results of the interim periods presented. The results of operations for the interim periods are not necessarily indicative of the operating results for the full fiscal year or any future period. These financial statements should be read in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended June 27, 2020. The consolidated financial statements include our financial statements and those of our wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated upon consolidation. Our fiscal year is the 52- or 53-week period ending on the last Saturday in June. Our fiscal 2021 and 2020 are 52-week periods ending June 26, 2021 and June 27, 2020, respectively. The fiscal periods presented in this report are 13-week and 26-week periods ended December 26, 2020, and December 28, 2019, respectively. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, allowance for doubtful accounts, cost of revenue, inventories, loss on purchase commitments, product warranty, accrued liabilities, share-based compensation costs, provision for income taxes, deferred income tax asset valuation allowances, uncertain tax positions, goodwill, intangible assets, investments and loss contingencies. We base our estimates on historical experience, applicable laws and regulations, and various other assumptions that we believe to be reasonable under the circumstances, including our expectations regarding the potential impacts on our business of the COVID-19 pandemic, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. Cash Equivalents and Short-Term Investments Cash equivalents consist of highly liquid investments with original maturities of three months or less. Our cash equivalents as of December 26, 2020 included bank deposits with a carrying value of $0.9 million, which approximates fair value, and as of June 27, 2020 they included money market accounts with a carrying value of $521.1 million, which approximates fair value, and are included in cash and cash equivalents on the condensed consolidated balance sheets. Short-term investments consist of bank deposits with original maturities of greater than three months but less than one year when purchased. All of our short-term investments are classified as investments recorded at amortized cost, which approximates fair value. Foreign Currency Transactions and Foreign Exchange Contracts The U.S. dollar is our functional and reporting currency. We remeasure our monetary assets and liabilities not denominated in the functional currency into U.S. dollar equivalents at the rate of exchange in effect on the balance sheet date. We measure and record non-monetary balance sheet accounts at the historical rate in effect at the date of transaction. We remeasure foreign currency expenses at the weighted average exchange rate in the month that the transaction occurred. Our foreign currency transactions and remeasurement gains and losses are included in selling, general, and administrative expenses in the condensed consolidated statements of income and resulted in net losses of $1.1 million and $1.0 million in the three and six months ended December 26, 2020, respectively, and net losses of $0.4 million and net gains of $0.1 million in the three and six months ended December 28, 2019, respectively. Leases We determine if a contract is a lease or contains a lease at the inception of the contract and reassess that conclusion if the contract is modified. All leases are assessed for classification as an operating lease or a finance lease. Operating lease right-of-use, or ROU, assets are included in non-current other assets on our condensed consolidated balance sheet. Operating lease liabilities are separated into a current portion, included within accrued liabilities on our condensed consolidated balance sheet, and a non-current portion, included within other long-term liabilities on our condensed consolidated balance sheet. We do not have any finance lease ROU assets or liabilities. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. We do not obtain and control the right to use the identified asset until the lease commencement date. Our lease liabilities are recognized at the applicable lease commencement date based on the present value of the lease payments required to be paid over the lease term. Because the interest rate implicit in the lease is not readily determinable, we generally use our incremental borrowing rate to discount the lease payments to present value. The estimated incremental borrowing rate is derived from information available at the lease commencement date. We factor in publicly available data for instruments with similar characteristics when calculating our incremental borrowing rates. Our ROU assets are also recognized at the applicable lease commencement date. The ROU asset equals the carrying amount of the related lease liability, adjusted for any lease payments made prior to lease commencement and lease incentives provided by the lessor. Variable lease payments are expensed as incurred and do not factor into the measurement of the applicable ROU asset or lease liability. The term of our leases equals the non-cancellable period of the lease, including any rent-free periods provided by the lessor, and also include options to renew or extend the lease (including by not terminating the lease) that we are reasonably certain to exercise. We establish the term of each lease at lease commencement and reassess that term in subsequent periods when one of the triggering events outlined in Topic 842 occurs. Operating lease cost for lease payments is recognized on a straight-line basis over the lease term. Our lease contracts often include lease and non-lease components. For our leases, we have elected the practical expedient offered by the standard to not separate lease from non-lease components and account for them as a single lease component. We have elected, for all classes of underlying assets, not to recognize ROU assets and lease liabilities for leases with a term of twelve months or less. Lease cost for short-term leases is recognized on a straight-line basis over the lease term.

Revenue Recognition

Revenue From Contract With Customer [Abstract]
Revenue Recognition	2. Revenue Recognition We account for revenue using Accounting Standards Codification Topic 606, or ASC 606, Revenue from Contracts with Customers. Our revenue is primarily generated from the sale of application specific integrated circuit chips, or ASIC chips, either directly to a customer or to a distributor. Revenues are recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to receive in exchange for those goods or services. All of our revenue, except an inconsequential amount, is recognized at a point in time, either on shipment or delivery of the product, depending on customer terms and conditions. We generally warrant our products for a period of 12 months from the date of sale and estimate probable product warranty costs at the time we recognize revenue as the warranty is considered an assurance warranty and not a performance obligation. Non-product revenue is recognized over the same period of time such performance obligations are satisfied. We then select an appropriate method for measuring satisfaction of the performance obligations. Revenue from sales to distributors is recognized upon shipment of the product to the distributors (sell-in basis). Master sales agreements are in place with certain customers, and these agreements typically contain terms and conditions with respect to payment, delivery, warranty and supply. In the absence of a master sales agreement, we consider a customer's purchase order or our standard terms and conditions to be the contract with the customer. Our pricing terms are negotiated independently, on a stand-alone basis. In determining the transaction price, we evaluate whether the price is subject to refund or adjustment to determine the net consideration which we expect to receive for the sale of such products. In limited situations, we make sales to certain customers under arrangements where we grant stock rotation rights, price protection and price allowances; variable consideration associated with these rights is expected to be inconsequential. These adjustments and incentives are accounted for as variable consideration, classified as other current liabilities under the revenue standard, other current assets . In limited circumstances , we enter into volume - based tiered pricing arrangements and we estimate total unit volumes under such arrangement s to determine the expected transaction price for the units expected to be transferred. Such arrangements are accounted for as contract liabilities within other accrued liabilities. Sales returns liabilities are recorded as refund liabilities within other accrued liabilities. Our accounts receivable balance is from contracts with customers and represents our unconditional right to receive consideration from customers. Payments are generally due within three months $0.2 We invoice customers for each delivery upon shipment and recognize revenue in accordance with delivery terms. As of December 26, 2020, we did not have any remaining unsatisfied performance obligations with an original duration greater than one year. Accordingly, under the optional exception provided by ASC 606, we do not disclose revenues allocated to future performance obligations of partially completed contracts. We account for shipping and handling costs as fulfillment costs before the customer obtains control of the goods and include these costs in We incur commission expense that is incremental to obtaining contracts with customers. Sales commissions (which are recorded as a selling, general and administrative expense in the condensed consolidated statements of income) are expensed when the product is shipped because such commissions are owed after shipment. Revenue from contracts with customers disaggregated by geographic area based on customer location and groups of similar products is presented in Note 14 Segment, Customers, and Geographical Information.

Our diluted net income per share amounts for each period presented include the weighted average effect of potentially dilutive shares. We use the treasury stock method to determine the dilutive effect of our stock options, restricted stock units, or RSUs, market stock units, or MSUs, performance stock units, or PSUs, and our convertible notes. Dilutive net income per share amounts do not include the potential weighted average effect of 179,491 and 775,347 shares of common stock related to certain share-based awards that were outstanding during the three months ended December 26, 2020 and December 28, 2019, respectively, and 502,657 and 1,074,778 shares of common stock related to certain share-based awards that were outstanding during the six months ended December 26, 2020 and December 28, 2019 , respectively . These share-based awards were not included in the computation of diluted net income per share because their effect would have been antidilutive.

Fair Value

Fair Value Disclosures [Abstract]
Fair Value	4. Fair Value Our carrying values of cash equivalents and short-term investments approximate their fair values due to the short period of time to maturity. The fair values of our accounts receivable and accounts payable approximate their carrying values because of the short-term nature of those instruments. Intangible assets, property and equipment, and goodwill are measured at fair value on a non-recurring basis if impairment is indicated. The interest rate on our bank debt is variable, which is subject to change from time to time to reflect a market interest rate; accordingly, the carrying value of our bank debt approximates fair value. The convertible notes are recorded at amortized cost of $496.1 million and $486.6 million as of December 26, 2020 and June 27, 2020, respectively and the fair value of the convertible notes was approximately $676.1 and $542.5 million as of December 26, 2020 and June 27, 2020, respectively, based on the last trading price of the convertible notes for the periods presented.

The effect of these write-downs is to establish a new cost basis in the related inventory, which we do not subsequently write up. We also record a liability and charge to cost of revenue for estimated losses on inventory we are obligated to purchase from our contract manufacturers when such losses become probable from customer delays, order cancellations, or other factors.

Acquisitions, Divestiture and Investment Acquisitions DisplayLink On July 17, 2020, we entered into a definitive agreement to acquire 100% of equity interest in DisplayLink Corporation, or DisplayLink, a leader in high-performance video compression technology, for $305 million in cash adjusted for (i) estimated cash and cash equivalents and short-term investments at the closing (ii) estimated indebtedness outstanding immediately prior to the closing, (iii) unpaid portion as of the closing of certain transaction expenses incurred by DisplayLink, and (iv) the amount that the estimated working capital of DisplayLink exceeds or falls short, respectively, of a certain specified target working capital set forth in an Agreement and Plan of Merger, or the Merger Agreement, with $3.1 million of the purchase price held in escrow accounts for adjustments after closing and to secure the Seller Parties’ indemnification obligations under the Merger Agreement. The acquisition closed on July 31, 2020, or the DisplayLink Closing Date, whereupon we obtained high-performance video compression technology which will further enhance our current IoT business. This acquisition has been accounted for using the purchase method of accounting in accordance with the business acquisition guidance. Under the purchase accounting method, the total estimated purchase consideration of the acquisition was allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their relative fair values. The excess of the purchase Our estimate of the fair values of the acquired intangible assets at December 26, 2020, is preliminary and subject to change and has been based on established and accepted valuation techniques performed with the assistance of our third-party valuation specialists. The primary areas of the preliminary purchase price allocation that are not yet finalized relate to the fair value of certain tangible assets acquired and liabilities assumed, the valuation of intangible assets acquired and related deferred income taxes. The Company expects to continue to obtain information for the purpose of determining the fair value of the net assets acquired at the acquisition date throughout the remainder of the measurement period . The adjusted purchase price paid for DisplayLink was $442.8 million. The following table summarizes the preliminary amounts recorded for the estimated fair values of the assets acquired and liabilities assumed as of the DisplayLink Closing Date (in millions): Cash and cash equivalents $ 40.9 Short-term investments 94.0 Accounts receivable, net 7.1 Inventory 33.1 Prepaid expenses and other current assets 9.1 Property and equipment 6.8 Intangible assets 193.0 Right-of-use lease asset 20.0 Non-current other assets 0.6 Total identifiable assets acquired 404.6 Accounts payable (5.2 ) Other accrued liabilities (9.9 ) Short-term lease liabilities (1.7 ) Long-term lease liabilities (18.2 ) Other long-term liabilities (31.8 ) Total liabilities (66.8 ) Net identifiable assets acquired 337.8 Goodwill 105.0 Net assets acquired $ 442.8 During the three months ended December 26, 2020, the Company recorded measurement period adjustments of $2.3 million to goodwill comprising of increases of $2.3 million in prepaid expenses and $0.4 million in other long-term liabilities for a net increase of $1.9 million to the fair value of other acquired net tangible assets. The following table summarizes the preliminary estimated fair value of the intangible assets as of the DisplayLink Closing Date (in millions): Estimated Weighted Average Useful Lives in Years Estimated Fair Value Developed technology 3.0 $ 82.0 Customer contracts and related relationships 3.0 54.0 In process research and development N/A 51.0 Trade names 4.0 3.0 Licensed technology 2.5 3.0 Estimated fair value of acquired intangibles $ 193.0 We estimated the fair value of the identified intangible assets using a discounted cash flow model for each of the underlying identified intangible assets. These fair value measurements were based on significant inputs not observable in the market and thus represent a Level 3 measurement. Key assumptions include the level and timing of expected future cash flows, conditions and demands specific to each intangible asset over its remaining useful life, and discount rates we believe to be consistent with the inherent risks associated with each type of asset, which range from 11.0% to 11.5%. The fair value of these intangible assets is primarily affected by the projected revenue, gross margins, operating expenses, the technology migration curve, customer ramp up period and the anticipated timing of the projected income associated with each intangible asset coupled with the discount rates used to derive their estimated present values. We believe the level and timing of expected future cash flows appropriately reflects market participant assumptions . In-process research and development consists of a next generation docking and video interface products for the IoT market. We expect to complete the in-process research and development project in early fiscal 2023. The value of goodwill reflects the anticipated synergies of the combined operations and workforce of DisplayLink as of the DisplayLink Closing Date. As of December 26, 2020, none of the goodwill is expected to be deductible for income tax purposes. Prior to the DisplayLink acquisition, we did not have an existing relationship or transactions with DisplayLink. The condensed consolidated financial statements include approximately $45.0 million of revenue from DisplayLink DisplayLink It is impracticable to determine the effect on net income attributable to DisplayLink as we integrated a substantial portion of DisplayLink into our ongoing operations during the first quarter of fiscal 2021 The following unaudited pro forma financial information (in millions, except per share data) presents the combined results of operations for us and DisplayLink as if the DisplayLink acquisition had occurred on June 30, 2019. The unaudited pro forma financial information has been prepared for comparative purposes only and does not purport to be indicative of the actual operating results that would have been recorded had the DisplayLink acquisition actually taken place on June 30, 2019 and should not be taken as indicative of future consolidated operating results. Additionally, the unaudited pro forma financial results do not include any anticipated synergies or other expected benefits from the DisplayLink acquisition. Three Months Ended Six Months Ended December December 2020 (1) 2019 2020 (1) 2019 Revenue $ 357.6 $ 414.1 $ 693.3 $ 779.1 Net income/(loss) 68.5 (10.6 ) 48.4 (6.3 ) (1) Includes results of Broadcom Wireless Connectivity Business Pro forma adjustments used to arrive at pro forma net income/(loss) included adjustments for historical amortization expense, the addition of intangible amortization expense for the value of intangibles under the purchase price allocation, transaction costs and restructuring costs. The total pro forma adjustments for the three months ended December 26, 2020 and December 28, 2019 were an increase to net income/(loss) of $6.9 million and a decrease of net income/(loss) of $9.7 million, respectively. The total pro forma adjustments for the six months ended December 26, 2020 and December 28, 2019 were an increase to net income/(loss) of $8.0 million and a decrease of net income/(loss) of $18.4 million, respectively. Broadcom Wireless Connectivity Business On July 2, 2020, we entered into definitive agreements with Broadcom to acquire certain assets and assume certain liabilities of, and obtain non-exclusive licenses relating to, Broadcom’s existing Wi-Fi, Bluetooth and GPS/GNSS products and business in the IoT market, or Broadcom Business Acquisition, for an aggregate consideration of $250 million in cash which closed on July 23, 2020, or the Broadcom Business Acquisition Closing Date. We also entered into certain transition agreements with Broadcom for a period of three years. We acquired these assets and assumed certain liabilities from Broadcom in order to obtain wireless connectivity technology which will enhance our current IoT business. The acquisition has been accounted for using the purchase method of accounting in accordance with the business acquisition guidance. Under the purchase accounting method, the total estimated purchase consideration of the acquisition was allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their relative fair values. The excess of the purchase consideration over the net tangible and identifiable intangible assets acquired and liabilities has been recorded as goodwill. Our estimate of the fair values of the acquired intangible assets at the Broadcom Business Acquisition Closing Date is preliminary and was based on established and accepted valuation techniques performed with the assistance of our third-party valuation specialists. The following table summarizes the adjusted purchase price paid for the Broadcom Business Acquisition (in millions): Cash $ 250.1 Adjustments to consideration transferred, net 1.5 Roadmap products - estimated cost of development (25.0 ) $ 226.6 We entered into a derivative and roadmap product agreement and an asset purchase agreement with Broadcom. The derivative and roadmap product agreement includes the purchase of derivative and roadmap product development services to be performed by Broadcom. We estimated the value of the development services to be approximately $25.0 million, accounted for it separate from the business combination, and included $10.0 million in prepaid expenses and other current assets and $15.0 million ($10.8 million after amortization as of December 26, 2020) in non-current other assets in our condensed consolidated balance sheets. The estimated value of the development services is amortizing over the period of time estimated to complete the development or approximately thirty months. The amortization of the estimated cost of development is included in research and development in our condensed consolidated statements of comprehensive income. In addition, under the terms of the asset purchase agreement we provided replacement equity compensation awards to the transferred employees and Broadcom agreed to make cash payments to transferred employees as incentive to accept employment offers from our company. We determined $3.5 million of value related to these arrangements should be included as consideration transferred, which was partially offset by $2.0 million of cash payments to transferred employees as a reduction of consideration transferred. The following table summarizes the amounts recorded for the estimated fair values of the assets acquired and liabilities assumed as of the Broadcom Business Acquisition Closing Date (in millions): Property and equipment $ 1.0 Acquired intangible assets 123.0 Total identifiable assets acquired 124.0 Liabilities assumed (0.2 ) Goodwill 102.8 Net assets acquired $ 226.6 We estimated the fair value of the identified intangible assets using a discounted cash flow model for each of the underlying identified intangible assets. These fair value measurements were based on significant inputs not observable in the market and thus represent a Level 3 measurement. Key assumptions include the level and timing of expected future cash flows, conditions and demands specific to each intangible asset over its remaining useful life, and discount rates we believe to be consistent with the inherent risks associated with each type of asset, which is 2.2% for order backlog and 13.0% for the rest of the intangible assets. The fair value of these intangible assets is primarily affected by the projected revenue, gross margins, operating expenses, the technology migration curve, customer ramp up period and the anticipated timing of the projected income associated with each intangible asset coupled with the discount rates used to derive their estimated present values. We believe the level and timing of expected future cash flows appropriately reflects market participant assumptions. The following table summarizes the preliminary estimate of the intangible assets as of the Broadcom Business Acquisition Closing Date Estimated Weighted Average Useful Lives in Years Estimated Fair Value Developed technology 6.0 $ 93.0 Customer contracts and related relationships 6.0 18.0 Order backlog 0.5 12.0 Estimated fair value of acquired intangibles $ 123.0 The value of goodwill reflects the anticipated synergies of the combined operations and workforce of the transferred Broadcom Business assets as of the Broadcom Business Acquisition Closing Date. As of December 26, 2020, all of the goodwill is expected to be deductible for income tax purposes. Prior to the Broadcom Business Acquisition, we did not have an existing relationship or transactions with Broadcom. The condensed consolidated financial statements include approximately $39.4 million of revenue from the Broadcom Business Acquisition from the Broadcom Business Acquisition Closing Date through December 26, 2020. It is impracticable to determine the effect on net income attributable to the as we had integrated a substantial portion of the into our ongoing operations during the quarter We determined it is impractical to include pro forma information given the difficulty in obtaining the historical financial information for the Broadcom Business Acquisition as the business was part of Broadcom and did not have discrete financial information prior to the acquisition. Inclusion of such information would require us to make estimates and assumptions regarding the acquired business historical financial results that we believe may ultimately prove inaccurate. Divestiture In December 2020, we completed the sale of limited audio technology intangible assets, received a fully-paid up perpetual license back from the buyer and, as an element of the transaction, licensed other audio technology intangible assets to the buyer under a fully-paid up perpetual license arrangement. Under the asset purchase agreement and the intellectual property license agreement, we received $35.0 million in cash. The gain on the sale of the audio technology assets was $34.2 million. Investment In December 2020, we invested $5.0 million in Eta Compute in exchange for preferred stock. This investment provides us with a partnership which enables us to better address expanded industry opportunities for artificial intelligence applications. The investment is accounted for under the cost method.

Indemnifications and Contingencies	10. Indemnifications and Contingencies Indemnifications In connection with certain agreements, we are obligated to indemnify the counterparty against third party claims alleging infringement of certain intellectual property rights by us. We have also entered into indemnification agreements with our officers and directors. Maximum potential future payments under these agreements cannot be estimated because these agreements generally do not have a maximum stated liability. However, historical costs related to these indemnification provisions have not been significant. We have not recorded any liability in our condensed consolidated financial statements for such indemnification obligations. Contingencies We have in the past, and may in the future, receive notices from third parties that claim our products infringe their intellectual property rights. We cannot be certain that our technologies and products do not and will not infringe issued patents or other proprietary rights of third parties. Any infringement claims, with or without merit, could result in significant litigation costs and diversion of management and financial resources, including the payment of damages, which could have a material adverse effect on our business, financial condition, and results of operations.

Debt

Debt Disclosure [Abstract]
Debt	11. Debt Convertible Debt Our convertible debt consists of an original $525 million aggregate principal amount of 0.50% convertible senior notes due 2022, or the Notes, which were issued in a private placement transaction. The net proceeds from the Notes, after deducting discounts, were $514.5 million. The Notes bear interest at a rate of 0.50% per year, which is payable semi-annually in arrears, on June 15 and December 15 of each year. The Notes are senior unsecured obligations and rank senior in right of payment to any of our indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to any our liabilities that are not so subordinated; effectively junior in right of payment to any of our secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of our subsidiaries. The Notes mature on June 15, 2022, or the Maturity Date, unless earlier repurchased, redeemed or converted. Holders may convert all or any portion of their Notes, in multiples of $1,000 principal amounts, at their option at any time prior to the close of business on the business day immediately preceding March 15, 2022 under certain defined circumstances, including (1) if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter or (2) during the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day. On or after March 15, 2022 until the close of business on the business day immediately preceding the Maturity Date, holders may convert all or any portion of their Notes, in multiples of $1,000 principal amounts, at the option of the holder. Upon conversion, we will pay or deliver, at our election, shares of common stock, cash, or a combination of cash and shares of common stock. The conversion rate for the Notes is initially 13.6947 shares of common stock per $1,000 principal amount of Notes (equivalent to an initial conversion price of approximately $73.02 per share of common stock). The conversion rate is subject to adjustment in certain circumstances. Upon the occurrence of a fundamental change (as defined in the Notes indenture), holders of the Notes may require us to repurchase for cash all or a portion of their Notes at a fundamental change repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest up to, but excluding, the fundamental change repurchase date. Commencing June 20, 2020, we may redeem for cash all or any portion of the Notes, at our option, if the last reported sale price of our common stock, as determined by us, has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest up to, but excluding, the redemption date. Our policy is to settle the principal amount of our Notes with cash upon conversion or redemption. As of the issuance date of the Notes, we recorded $82.1 million of the principal amount to equity, representing the debt discount for the difference between our estimated nonconvertible debt borrowing rate of 4.39% and the coupon rate of the Notes of 0.50% using a five-year The contractual interest expense and amortization of discount on the Notes for the six months ended December 26, 2020, were as follows (in millions): Six Months Ended December 2020 Interest expense $ 1.3 Amortization of discount and debt issuance costs 9.5 Total interest $ 10.8 The unamortized amounts of the debt issuance costs and discount associated with the Notes as of December 26, 2020 were $2.9 million and $26.0 million, respectively. Revolving Credit Facility In February 2020, we entered into the First Amendment to Amended and Restated Credit Agreement, or the Amendment, with the lenders that are party thereto, or the Lenders, and Wells Fargo Bank, National Association, as administrative agent for the Lenders, related to that certain Amended and Restated Credit Agreement, dated September 27, 2017, or the Credit Agreement. Pursuant to the Amendment, the Credit Agreement was amended to, among other things, (i) modify the definition of Consolidated EBITDA (as defined in the Credit Agreement) to increase the maximum limit on the add back of certain restructuring and integration cost and expenses to 30% from 15% of Consolidated EBITDA, (ii) modify the negative covenant for Consolidated Total Leverage Ratio (as defined in the Credit Agreement) at the end of any fiscal quarter to 4.75:1.00 from 3.50:1.00, and for any four quarter period following a Material Acquisition (as defined in the Credit Agreement) to 5:00:1.00 from 3.75:1.00, (iii) modify the circumstances under which the maturity date of the Credit Agreement would be accelerated in advance of the maturity date of the Notes to eliminate the acceleration of the maturity date of the Credit Agreement if we meet certain specified leverage and liquidity covenants, (iv) add a minimum liquidity covenant for each two-week period beginning on the date that is 120 days prior to the maturity date of the Notes, (v) add certain technical amendments to address LIBOR transition matters, and (vi) include or revise certain definitions and certain customary representation, warranties and acknowledgments. The Credit Agreement provides for a revolving credit facility in a principal amount of up to $200 million, which includes a $20 million sublimit for letters of credit and a $20 million sublimit for swingline loans. Under the terms of the Credit Agreement, we may, subject to the satisfaction of certain conditions, request increases in the revolving credit facility commitments in an aggregate principal amount of up to $100 million to the extent existing or new lenders agree to provide such increased or additional commitments, as applicable. Future proceeds under the revolving credit facility are available for working capital and general corporate purposes. As of December 26, 2020, there was a $100.0 million balance outstanding under the revolving credit facility. The weighted average annualized interest rate on these borrowings for the three months ended December 26, 2020 was 2.73%. The revolving credit facility is required to be repaid in full on the earlier of (i) September 27, 2022, and (ii) the date 91 days prior to the Maturity Date of the Notes if the Notes have not been refinanced in full by such date, subject to certain exceptions. Debt issuance costs relating to the revolving credit facility of $2.3 million, included in non-current other assets on our consolidated balance sheet, are being amortized over 60 months. Our obligations under the Credit Agreement are guaranteed by the material domestic subsidiaries of our company, subject to certain exceptions (such material subsidiaries, together with our company, collectively, the Credit Parties). The obligations of the Credit Parties under the Credit Agreement and the other loan documents delivered in connection therewith are secured by a first priority security interest in substantially all of the existing and future personal property of the Credit Parties, including, without limitation, 65% of the voting capital stock of certain of the Credit Parties’ direct foreign subsidiaries, subject to certain exceptions. The revolving credit facility bears interest at our election of a Base Rate plus an Applicable Margin or LIBOR plus an Applicable Margin. Swingline loans bear interest at a Base Rate plus an Applicable Margin. The Base Rate is a floating rate that is the greater of the Prime Rate, the Federal Funds Rate plus 50 basis points, or LIBOR plus 100 basis points. The Applicable Margin is based on a sliding scale which ranges from 0.25 to 100 basis points for Base Rate loans and 100 basis points to 175 basis points for LIBOR loans. We are required to pay a commitment fee on any unused commitments under the Credit Agreement which is determined on a leverage-based sliding scale ranging from 0.175% to 0.25% per annum. Interest and fees are payable on a quarterly basis. The LIBOR index is expected to be discontinued at the end of 2021. Under our credit facility, when the LIBOR index is discontinued, we will switch to a comparable or successor rate as selected by us and the Administrative Agent, which may include the Secured Overnight Financing Rate, or SOFR. Under the Credit Agreement, there are various restrictive covenants, including three financial covenants which limit the consolidated total leverage ratio, or leverage ratio, the consolidated interest coverage ratio, or interest coverage ratio, a restriction which places a limit on the amount of capital expenditures that may be made in any fiscal year, a restriction that permits up to $50 million per fiscal quarter of accounts receivable financings, and sets the Specified Leverage Ratio. The leverage ratio is the ratio of debt as of the measurement date to earnings before interest, taxes, depreciation and amortization, or EBITDA, for the four consecutive quarters ending with the quarter of measurement. The current leverage ratio shall not exceed 4.75 to 1.00 provided that for the four fiscal quarters ending after the date of a material acquisition, such maximum leverage ratio shall be adjusted to 5.0 to 1.00, and thereafter 4.75 to 1.0. The interest coverage ratio is EBITDA to interest expense for the four consecutive quarters ending with the quarter of measurement. The interest coverage ratio must not be less than 3.50 to 1.0 during the term of the Credit Agreement. The Specified Leverage Ratio is the ratio used in determining, among other things, whether we are permitted to make dividends and/or prepay certain indebtedness, at a fixed ratio of 2.25 to 1.00. As of December 26, 2020, we remain in compliance with the restrictive covenants.

An individual was eligible to receive an award under the 2019 Inducement Equity Plan only if he or she was not previously an employee or director of our Company (or is returning to work after a bona-fide period of non-employment), and an award under the 2019 Inducement Equity Plan is a material inducement for him or her to accept employment with our Company. As a result of approval by our stockholders of our amended and restated 2019 Incentive Plan on October 27, 2020, no new awards will be granted under the 2019 Inducement Equity Plan. Stock Options Stock option activity was as follows: Stock Weighted Aggregate Option Average Intrinsic Awards Exercise Value Outstanding Price (in millions) Outstanding as of June 2020 329,786 $ 69.78 Exercised (76,060 ) 61.73 Expired (53,561 ) 75.48 Outstanding and Exercisable as of December 2020 200,165 71.31 $ 3.1 The aggregate intrinsic value was determined using the closing price of our common stock on December 24, 2020 of $86.15 and excludes the impact of stock options that were not in-the-money.

Of the shares delivered, 151,595 shares valued at $11.8 million were withheld to meet statutory tax withholding requirements. Market Stock Units Our 2019 Incentive Plan and our Amended and Restated 2010 Incentive Compensation Plan provide for the grant of MSU awards to our employees, consultants, and directors, and our 2019 Inducement Equity Plan provides for the grant of MSU awards to certain of our employees. An MSU is a promise to deliver shares of our common stock at a future date based on the achievement of market-based performance requirements in accordance with the terms of the MSU grant agreement. We have granted MSU awards to our executive officers and other management members under our Amended and Restated 2010 Incentive Compensation Plan, our 2019 Incentive Plan and our 2019 Inducement Equity Plan, which are designed to vest in three or four tranches with the target quantity for each tranche equal to one-third one-fourth one-year two-year three-year four-year For MSU awards granted in fiscal 2021, performance is measured based on our achievement of a specified level of total stockholder return, or TSR, relative to the TSRs of each company in the Russell 2000 Index. The potential payout ranges from 0% to 200% of the target grant quantity based on our TSR performance relative to the TSRs of each company in the Russell 2000 Index. No payout will occur if our TSR performance falls below the 25 th th th th th For MSU awards granted in fiscal 2021, the first tranche and the second tranche can payout up to 200%, and the payout for the third tranche will be calculated based on the total target quantity for the entire grant multiplied by the payout factor, based on performance for the three-year performance period, less shares issued for the first tranche and the second tranche. For outstanding MSU awards granted prior to fiscal 2021, performance is measured based on our achievement of a specified level of TSR relative to the TSR of the S&P Semiconductor Select Industry Index, or SPSISC Index. The potential payout ranges from 0% to 200% of the target grant quantity and is adjusted on a two For MSU awards granted prior to fiscal 2021 and vesting over three years, the payout for the first tranche and the second tranche will not exceed 100% and the payout for the third tranche will be calculated based on the total target quantity for the entire grant multiplied by the payout factor, based on performance for the three-year performance period, less shares issued for the first tranche and the second tranche. For MSUs vesting over four years, the payout for the first tranche, the second tranche and the third tranche will not exceed 100% and the payout for the fourth tranche will be calculated based on the total target quantity for the entire grant multiplied by the payout factor, based on performance for the four-year performance period, less shares issued for the first tranche, the second tranche and the third tranche. Delivery of shares earned, if any, will take place on the dates provided in the applicable MSU grant agreement, assuming the grantee is still an employee, consultant, or director of our Company at the end of the applicable performance period. On the delivery date, we withhold shares to cover statutory tax withholding requirements and deliver a net quantity of shares to the employee, consultant, or director after such withholding. Until delivery of shares, the grantee has no rights as a stockholder with respect to any shares underlying the MSU award. MSU activity was as follows: Aggregate MSU Intrinsic Awards Value Outstanding (in millions) Balance as of June 2020 391,532 Granted 101,009 Performance adjustment 77,534 Delivered (208,275 ) Forfeited (14,773 ) Balance as of December 2020 347,027 $ 29.9 The aggregate intrinsic value was determined using the closing price of our common stock on December 24, 2020 of $86.15. We value MSUs using the Monte Carlo simulation model on the date of grant and amortize the compensation expense over the three- or four-year performance and service period on a ratable basis. The unrecognized share-based compensation cost of our outstanding MSUs was approximately $23.8 million as of December 26, 2020, which will be recognized over a weighted average period of approximately 1.5 years. Performance Stock Units Our 2019 Incentive Plan and our Amended and Restated 2010 Incentive Compensation Plan provide for the grant of PSU awards to our employees, consultants, and directors. A PSU is a promise to deliver shares of our common stock at a future date based on the achievement of performance-based requirements in accordance with the terms of the PSU grant agreement. We have granted PSUs to our executive officers and other management members under our Amended and Restated 2010 Incentive Compensation Plan, our 2019 Incentive Plan and our 2019 Inducement Equity Plan, which are designed to vest in three tranches with the target quantity for each tranche equal to one-third Delivery of shares earned, if any, will take place on the dates provided in the applicable PSU grant agreement, assuming the grantee is still an employee, consultant, or director of our Company at the end of the applicable service period. On the delivery date, we withhold shares to cover statutory tax withholding requirements and deliver a net quantity of shares to the employee, consultant, or director after such withholding. Until delivery of shares, the grantee has no rights as a stockholder with respect to any shares underlying the PSU award. PSU activity was as follows: Aggregate PSU Intrinsic Awards Value Outstanding (in millions) Balance as of June 2020 333,848 Awarded 174,231 Performance adjustment 84,111 Released (201,835 ) Forfeited (48,671 ) Balance as of December 2020 341,684 $ 29.4 The aggregate intrinsic value was determined using the closing price of our common stock on December 24, 2020 of $86.15. We value PSUs using the aggregate intrinsic value on the date of grant adjusted for estimated performance achievement during the performance period and amortize the compensation expense over the three-year Phantom Stock Units The 2019 Incentive Plan authorizes the grant of phantom stock units to non-employee directors, officers and employees. We initially granted phantom stock units in October 2019. Phantom stock units are cash-settled and entitle the recipient to receive a cash payment equal to the value of a single share for each unit based on the average closing share price of our stock over the thirty calendar days prior to the vesting date. Grants of phantom stock units vest over three years, with an annual vesting date of October 31 each year subsequent to the grant date. We recognize compensation expense for phantom stock units on a straight-line basis for each tranche of each award based on the average closing price of our common stock over the thirty calendar days ended prior to each balance sheet date. The outstanding phantom stock units had a fair value of $81.31 per unit at December 26, 2020 and our accrued liability for such units was $2.8 million. Phantom stock activity was as follows: Phantom Stock Units Outstanding Balance as of June 2020 789,113 Released (242,692 ) Forfeited (100,709 ) Balance as of December 2020 445,712 The unrecognized share-based compensation cost of our outstanding phantom stock units was approximately $33.5 million as of December 26, 2020, which will be recognized over a weighted average period of approximately 1.9 years.

Income Tax Disclosure [Abstract]
Income Taxes	13. Income Taxes On March 27, 2020, the Coronavirus Aid, Relief and Economic Security, or CARES, Act was enacted and signed into law. The CARES Act did not have a material impact on the income tax provision for the six months ended December 26, 2020. We account for income taxes under the asset and liability method. The provision for income taxes recorded in interim periods is based on our estimate of the annual effective tax rate applied to year-to-date income before provision for income taxes, adjusted for discrete items required to be recognized in the period in which they are incurred. In each quarter, we update our estimate of the annual effective tax rate, and if the estimated annual tax rate changes, we make a cumulative adjustment in that quarter. Our quarterly tax provision and our quarterly estimate of the annual effective tax rate can be subject to volatility due to several factors, including our ability to accurately forecast annual income before provision for income taxes in each of the tax jurisdictions in which we operate. The provision for income taxes of $2.4 million and $12.0 million for the three months ended December 26, 2020 and December 28, 2019, respectively, represented estimated federal, foreign, and state income taxes. The effective tax rate for the three months ended December 26, 2020 diverged from the combined U.S. federal and state statutory tax rate primarily because of foreign withholding taxes, non-deductible officer compensation, the impact of accounting for qualified stock options and global intangible low-taxed income, or GILTI, partially offset by the benefit of income taxed at lower rates, research credits and foreign tax credits. The effective tax rate for the three months ended December 28, 2019, diverged from the combined U.S. federal and state statutory tax rate, primarily because of foreign withholding taxes and GILTI partially offset by the benefit of research credits, foreign tax credits and income taxed at lower tax rates. The provision for income taxes of $6.0 million and $7.1 million for the six months ended December 26, 2020 and December 28, 2019, respectively, represented estimated federal, foreign, and state income taxes. The effective tax rate for the three months ended December 26, 2020 diverged from the combined U.S. federal and state statutory tax rate primarily because of foreign withholding taxes, non-deductible officer compensation, the impact of accounting for qualified stock options and GILTI partially offset by the benefit of income taxed at lower rates, research credits and foreign tax credits. The effective tax rate for the six months ended December 28, 2019, diverged from the combined U.S. federal and state statutory tax rate, primarily because of withholding taxes and GILTI partially offset by the benefit of research credits, foreign tax credits and income taxed at lower tax rates. The total liability for gross unrecognized tax benefits related to uncertain tax positions remained unchanged during the six months ended December 26, 2020, at $22.1 million, and was included in other long-term liabilities on our condensed consolidated balance sheets. If recognized, the total gross unrecognized tax benefits would reduce the effective tax rate on income from continuing operations. Accrued interest and penalties related to unrecognized tax benefits as of December 26, 2020 were $1.7 million; this balance decreased by $0.3 million compared to June 27, 2020, largely due to the expiration of the relevant statute of limitations. We classify interest and penalties as components of income tax expense. It is reasonably possible that the amount of the liability for unrecognized tax benefits may change within the next twelve months and an estimate of the range of possible changes includes an increase in our liability of up to $3.2 million. Any prospective adjustments to our unrecognized tax benefits will be recorded as an increase or decrease to income tax expense and cause a corresponding change to our effective tax rate. Accordingly, our effective tax rate could fluctuate materially from period to period. Our major tax jurisdictions are the United States, Hong Kong SAR, Japan and the United Kingdom. From fiscal 2014 onward, we remain subject to examination by one or more of these jurisdictions.

Basis of Presentation (Policies

Basis of Presentation (Policies)	6 Months Ended
	Dec. 31, 2020
Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates, including those related to revenue recognition, allowance for doubtful accounts, cost of revenue, inventories, loss on purchase commitments, product warranty, accrued liabilities, share-based compensation costs, provision for income taxes, deferred income tax asset valuation allowances, uncertain tax positions, goodwill, intangible assets, investments and loss contingencies. We base our estimates on historical experience, applicable laws and regulations, and various other assumptions that we believe to be reasonable under the circumstances, including our expectations regarding the potential impacts on our business of the COVID-19 pandemic, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.
Cash Equivalents and Short Term Investments	Cash Equivalents and Short-Term Investments Cash equivalents consist of highly liquid investments with original maturities of three months or less. Our cash equivalents as of December 26, 2020 included bank deposits with a carrying value of $0.9 million, which approximates fair value, and as of June 27, 2020 they included money market accounts with a carrying value of $521.1 million, which approximates fair value, and are included in cash and cash equivalents on the condensed consolidated balance sheets. Short-term investments consist of bank deposits with original maturities of greater than three months but less than one year when purchased. All of our short-term investments are classified as investments recorded at amortized cost, which approximates fair value.
Foreign Currency Transactions and Foreign Exchange Contracts	Foreign Currency Transactions and Foreign Exchange Contracts The U.S. dollar is our functional and reporting currency. We remeasure our monetary assets and liabilities not denominated in the functional currency into U.S. dollar equivalents at the rate of exchange in effect on the balance sheet date. We measure and record non-monetary balance sheet accounts at the historical rate in effect at the date of transaction. We remeasure foreign currency expenses at the weighted average exchange rate in the month that the transaction occurred. Our foreign currency transactions and remeasurement gains and losses are included in selling, general, and administrative expenses in the condensed consolidated statements of income and resulted in net losses of $1.1 million and $1.0 million in the three and six months ended December 26, 2020, respectively, and net losses of $0.4 million and net gains of $0.1 million in the three and six months ended December 28, 2019, respectively.
Leases	Leases We determine if a contract is a lease or contains a lease at the inception of the contract and reassess that conclusion if the contract is modified. All leases are assessed for classification as an operating lease or a finance lease. Operating lease right-of-use, or ROU, assets are included in non-current other assets on our condensed consolidated balance sheet. Operating lease liabilities are separated into a current portion, included within accrued liabilities on our condensed consolidated balance sheet, and a non-current portion, included within other long-term liabilities on our condensed consolidated balance sheet. We do not have any finance lease ROU assets or liabilities. ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. We do not obtain and control the right to use the identified asset until the lease commencement date. Our lease liabilities are recognized at the applicable lease commencement date based on the present value of the lease payments required to be paid over the lease term. Because the interest rate implicit in the lease is not readily determinable, we generally use our incremental borrowing rate to discount the lease payments to present value. The estimated incremental borrowing rate is derived from information available at the lease commencement date. We factor in publicly available data for instruments with similar characteristics when calculating our incremental borrowing rates. Our ROU assets are also recognized at the applicable lease commencement date. The ROU asset equals the carrying amount of the related lease liability, adjusted for any lease payments made prior to lease commencement and lease incentives provided by the lessor. Variable lease payments are expensed as incurred and do not factor into the measurement of the applicable ROU asset or lease liability. The term of our leases equals the non-cancellable period of the lease, including any rent-free periods provided by the lessor, and also include options to renew or extend the lease (including by not terminating the lease) that we are reasonably certain to exercise. We establish the term of each lease at lease commencement and reassess that term in subsequent periods when one of the triggering events outlined in Topic 842 occurs. Operating lease cost for lease payments is recognized on a straight-line basis over the lease term. Our lease contracts often include lease and non-lease components. For our leases, we have elected the practical expedient offered by the standard to not separate lease from non-lease components and account for them as a single lease component. We have elected, for all classes of underlying assets, not to recognize ROU assets and lease liabilities for leases with a term of twelve months or less. Lease cost for short-term leases is recognized on a straight-line basis over the lease term.

The derivative and roadmap product agreement includes the purchase of derivative and roadmap product development services to be performed by Broadcom. We estimated the value of the development services to be approximately $25.0 million, accounted for it separate from the business combination, and included $10.0 million in prepaid expenses and other current assets and $15.0 million ($10.8 million after amortization as of December 26, 2020) in non-current other assets in our condensed consolidated balance sheets. The estimated value of the development services is amortizing over the period of time estimated to complete the development or approximately thirty months. The amortization of the estimated cost of development is included in research and development in our condensed consolidated statements of comprehensive income. In addition, under the terms of the asset purchase agreement we provided replacement equity compensation awards to the transferred employees and Broadcom agreed to make cash payments to transferred employees as incentive to accept employment offers from our company. We determined $3.5 million of value related to these arrangements should be included as consideration transferred, which was partially offset by $2.0 million of cash payments to transferred employees as a reduction of consideration transferred.

Covenant description	Pursuant to the Amendment, the Credit Agreement was amended to, among other things, (i) modify the definition of Consolidated EBITDA (as defined in the Credit Agreement) to increase the maximum limit on the add back of certain restructuring and integration cost and expenses to 30% from 15% of Consolidated EBITDA, (ii) modify the negative covenant for Consolidated Total Leverage Ratio (as defined in the Credit Agreement) at the end of any fiscal quarter to 4.75:1.00 from 3.50:1.00, and for any four quarter period following a Material Acquisition (as defined in the Credit Agreement) to 5:00:1.00 from 3.75:1.00, (iii) modify the circumstances under which the maturity date of the Credit Agreement would be accelerated in advance of the maturity date of the Notes to eliminate the acceleration of the maturity date of the Credit Agreement if we meet certain specified leverage and liquidity covenants, (iv) add a minimum liquidity covenant for each two-week period beginning on the date that is 120 days prior to the maturity date of the Notes, (v) add certain technical amendments to address LIBOR transition matters, and  (vi) include or revise certain definitions and certain customary representation, warranties and acknowledgments		Under the Credit Agreement, there are various restrictive covenants, including three financial covenants which limit the consolidated total leverage ratio, or leverage ratio, the consolidated interest coverage ratio, or interest coverage ratio, a restriction which places a limit on the amount of capital expenditures that may be made in any fiscal year, a restriction that permits up to $50 million per fiscal quarter of accounts receivable financings, and sets the Specified Leverage Ratio. The leverage ratio is the ratio of debt as of the measurement date to earnings before interest, taxes, depreciation and amortization, or EBITDA, for the four consecutive quarters ending with the quarter of measurement. The current leverage ratio shall not exceed 4.75 to 1.00 provided that for the four fiscal quarters ending after the date of a material acquisition, such maximum leverage ratio shall be adjusted to 5.0 to 1.00, and thereafter 4.75 to 1.0. The interest coverage ratio is EBITDA to interest expense for the four consecutive quarters ending with the quarter of measurement. The interest coverage ratio must not be less than 3.50 to 1.0 during the term of the Credit Agreement. The Specified Leverage Ratio is the ratio used in determining, among other things, whether we are permitted to make dividends and/or prepay certain indebtedness, at a fixed ratio of 2.25 to 1.00.  As of December 26, 2020, we remain in compliance with the restrictive covenants
