Business Combinations [Abstract]
Acquisitions	2. ACQUISITIONS Acquisition of FiBest Limited— We recognize the FiBest assets acquired and liabilities assumed based upon the fair value of such assets and liabilities measured as of the date of acquisition. The aggregate purchase price for FiBest is being allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The excess of the purchase price over the fair value of the acquired net assets represents cost and revenue synergies specific to the Company, as well as non-capitalizable intangible assets, such as the employee workforce acquired, and has been allocated to goodwill, none of which will be tax deductible. We expect to finalize our allocation of purchase price during calendar year 2016. The preliminary allocation of purchase price as of January 1, 2016, is as follows (in thousands): Preliminary Current assets $ 10,850 Intangible assets 45,650 Other assets 3,334 Total assets acquired 59,834 Liabilities assumed: Debt 11,627 Deferred income taxes 12,932 Other liabilities 3,968 Total liabilities assumed 28,527 Net assets acquired 31,307 Consideration: Cash paid upon closing, net of cash acquired 47,517 Goodwill $ 16,210 The components of the acquired intangible assets on a preliminary basis were as follows (in thousands): Amount Useful Lives Developed technology $ 9,400 7 Customer relationships 36,250 10 $ 45,650 The overall weighted-average life of the identified intangible assets acquired in the FiBest Acquisition is estimated to be 9.4 years and the assets are being amortized over their estimated useful lives based upon the pattern over which we expect to receive the economic benefit from these assets. The purchase accounting is preliminary and subject to completion including the areas of taxation and certain fair value measurements, particularly the finalization of the valuation assessment of the acquired tangible and intangible assets. The adjustments arising from the completion of the outstanding matters may materially affect the preliminary purchase accounting. The following is a summary of FiBest revenue and earnings included in MACOM’s accompanying condensed consolidated statements of operations for three months ended January 1, 2016 (in thousands): Three Months Ended Revenue $ 2,670 Loss before income taxes (811 ) Unaudited Supplemental Pro Forma Data— Three Months Ended January 1, 2016 January 2, 2015 Revenue $ 123,400 $ 103,888 Net loss (15,127 ) (9,833 ) Acquisition of Aeroflex/Metelics Inc.— We are recognizing the Metelic’s assets acquired and liabilities assumed based upon the fair value of such assets and liabilities measured as of the date of acquisition. The aggregate purchase price for Metelics is being allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The excess of the purchase price over the fair value of the acquired net assets represents cost and revenue synergies specific to the Company, as well as non-capitalizable intangible assets, such as the employee workforce acquired, and has been allocated to goodwill, which will be tax deductible due to a 338 (h) (10) election. We expect to finalize our allocation of purchase price during calendar year 2016. The preliminary allocation of purchase price as of January 1, 2016, is as follows (in thousands): Preliminary Current assets $ 15,250 Intangible assets 19,700 Other assets 6,249 Total assets acquired 41,199 Liabilities assumed: Other liabilities 7,401 Total liabilities assumed 7,401 Net assets acquired 33,798 Consideration: Cash paid upon closing, net of cash acquired 38,000 Goodwill $ 4,202 The components of the acquired intangible assets on a preliminary basis were as follows (in thousands): Amount Useful Lives Developed technology $ 1,000 7 Customer relationships 18,700 10 $ 19,700 The overall weighted-average life of the identified intangible assets acquired in the Metelics Acquisition is estimated to be 9.8 years and the assets are being amortized over their estimated useful lives based upon the pattern over which we expect to receive the economic benefit from these assets. The purchase accounting is preliminary and subject to completion including certain fair value measurements, particularly the finalization of the valuation assessment of the acquired tangible and intangible assets. The adjustments arising from the completion of the outstanding matters may materially affect the preliminary purchase accounting. The following is a summary of Metelics revenue and earnings included in MACOM’s accompanying condensed consolidated statements of operations for the three months ended January 1, 2016 (in thousands): Three Months Ended Revenue $ 1,907 Loss before income taxes (46 ) Unaudited Supplemental Pro Forma Data— Three Months Ended January 1, 2016 January 2, 2015 Revenue $ 124,610 $ 107,384 Net loss (15,583 ) (7,207 ) Acquisition of BinOptics Corporation— exchanged for aggregate consideration of approximately $208.4 million in cash. In addition we paid $14.6 million as part of a related retention escrow agreement designed to retain certain BinOptics employees. This $14.6 million was included in the terms of the purchase agreement and has been accounted for as a post-closing prepaid expense. We funded the BinOptics Acquisition with a combination of cash on hand and the incurrence of $100.0 million of additional borrowings under our existing Revolving Facility. For the three months ended January 2, 2015, we recorded transaction costs of $4.6 million related to the BinOptics Acquisition. The BinOptics Acquisition was accounted for as a stock purchase and the operations of BinOptics have been included in our consolidated financial statements since the date of acquisition. We have recognized BinOptics’ assets acquired and liabilities assumed based upon the fair value of such assets and liabilities measured as of the date of acquisition. The aggregate purchase price for BinOptics has been allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The excess of the purchase price over the fair value of the acquired net assets represents cost and revenue synergies specific to the Company, as well as non-capitalizable intangible assets, such as the employee workforce acquired, and has been allocated to goodwill, none of which is tax deductible. The Company finalized its allocation of purchase price during the first quarter of fiscal year 2016. The final allocation of purchase price as of January 1, 2016, is as follows (in thousands): October 2, Allocation January 1, Current assets $ 23,674 $ (1,100 ) $ 22,574 Intangible assets 136,900 400 137,300 Other assets 9,194 — 9,194 Total assets acquired 169,768 (700 ) 169,068 Liabilities assumed: Debt 2,535 — 2,535 Deferred income taxes 33,345 99 33,444 Other liabilities 13,106 — 13,106 Total liabilities assumed 48,986 99 49,085 Net assets acquired 120,782 (799 ) 119,983 Consideration: Cash paid upon closing, net of cash acquired 208,352 — 208,352 Goodwill $ 87,570 $ 799 $ 88,369 The components of the acquired intangible assets were as follows (in thousands): Amount Useful Lives Developed technology $ 17,500 7 Customer relationships 119,800 10 $ 137,300 The overall weighted-average life of the identified intangible assets acquired in the BinOptics Acquisition is estimated to be 9.6 years and the assets are being amortized over their estimated useful lives based upon the pattern over which we expect to receive the economic benefit from these assets.

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	3. DISCONTINUED OPERATIONS In August 2015, we sold our Automotive business to Autoliv ASP Inc as the Automotive business was not consistent with our long-term strategic vision from both a growth and profitability perspective. The agreed consideration included $82.1 million in cash paid at closing, subject to customary working capital and other adjustments, $18.0 million payable in eighteen months pending resolution of any contingencies as part of an indemnification agreement, plus the opportunity to receive up to an additional $30.0 million in cash based on achievement of revenue-based earnout targets through 2019. Additionally, we entered into a Consulting Agreement pursuant to which we may provide Autoliv with certain non-design advisory services for a period of two years following the closing of the transaction for up to $15.0 million in cash. During fiscal year 2015, we recorded a pre-tax gain on the sale of the Automotive business of $61.8 million based on the $82.1 million received at closing on August 17, 2015 as described above. The remainder of the consideration to be received from Autoliv, if any, including any amounts related to the consulting agreement, will be accounted for in discontinued operations when the contingencies are finalized and the proceeds, if any, become realizable over the next several years. The accompanying consolidated statement of operations includes the following operating results related to these divested businesses (in thousands): Three Months Ended January 1, January 2, Revenue $ — $ 18,308 Cost of revenue — 11,526 Gross profit — 6,782 Operating expenses: Research and development — 692 Selling, general and administrative — 371 Restructuring charges — — Total operating expenses — 1,063 Income from discontinued operations — 5,719 Other income 1,875 — Gain on sale — — Income before income taxes 1,875 5,719 Income tax provision 676 2,062 Income from discontinued operations $ 1,199 $ 3,657 Above includes depreciation & amortization of $ — $ 66 Cashflow from Operating Activities (1,199 ) 1,516 Cashflow from Investing Activities — — Other income of $1.9 million was recorded during the three months ended January 1, 2016 related to the consulting agreement.

Fair Value

Fair Value	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value	5. FAIR VALUE We group our financial assets and liabilities measured at fair value on a recurring basis in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are: Level 1 Level 2 Level 3 Assets and Liabilities Measured and Recorded at Fair Value on a Recurring Basis We measure certain assets and liabilities at fair value on a recurring basis such as our financial instruments and derivatives. There have been no transfers between Level 1, 2 or 3 assets or liabilities during the three months ended January 1, 2016. Money market funds are actively traded and consist of highly liquid investments with original maturities of 90 days or less. They are measured at their net asset value (“NAV”) and classified as Level 1. Corporate and agency bonds are categorized as Level 2 assets except where sufficient quoted prices exist in active markets, in which case such securities are categorized as Level 1 assets. These securities are valued using third-party pricing services. These services may use, for example, model-based pricing methods that utilize observable market data as inputs. Broker dealer bids or quotes on securities with similar characteristics may also be used. The fair values of the contingent consideration liabilities were estimated based upon a risk-adjusted present value of the probability-weighted expected payments by us. Specifically, we considered base, upside and downside scenarios for the operating metrics upon which the contingent payments are to be based. Probabilities were assigned to each scenario and the probability-weighted payments were discounted to present value using risk-adjusted discount rates. The maximum possible payment of contingent consideration is $1.5 million. The fair value of the stock warrants has been estimated using a Black-Scholes option pricing model giving consideration to the quoted market price of the common stock on that date, an expected life of 5.0 years, expected volatility of 36.5% and risk free rate of 1.8%. Any significant change in these assumptions could have an impact on the value of the stock warrants. These estimates include significant judgments and actual results could materially differ and have a material impact upon the values of the recorded liabilities. Any changes in the estimated fair values of the liabilities in the future will be reflected in our earnings and such changes could be material. Assets and liabilities measured at fair value on a recurring basis consist of the following (in thousands): January 1, 2016 Fair Value Active Markets Observable Unobservable Assets Money market funds $ 1,000 $ 1,000 $ — $ — Agency bonds 10,045 — 10,045 — Corporate bonds 19,709 — 19,709 — Total assets measured at fair value $ 30,754 $ 1,000 $ 29,754 $ — Liabilities Contingent consideration $ 1,170 $ — $ — $ 1,170 Common stock warrant liability 36,700 — — 36,700 Total liabilities measured at fair value $ 37,870 $ — $ — $ 37,870 January 2, 2015 Fair Value Active Markets Observable Unobservable Assets Trading securities $ 250 $ — $ — $ 250 Total assets measured at fair value $ 250 $ — $ — $ 250 Liabilities Contingent consideration $ 820 $ — $ — $ 820 Common stock warrant liability 26,409 — — 26,409 Total liabilities measured at fair value $ 27,229 $ — $ — $ 27,229 The changes in assets and liabilities with inputs classified within Level 3 of the fair value hierarchy consist of the following (in thousands): October 2, Net Purchases and Issuances Sales and Settlements Transfers in and/or (out) of Level 3 January 1, Contingent consideration $ 1,150 $ 20 $ — $ — $ — $ 1,170 Common stock warrant liability $ 21,822 $ 14,878 $ — $ — $ — $ 36,700 October 3, Net Purchases and Issuances Sales and Settlements Transfers in and/or (out) of Level 3 January 2, Trading securities $ 250 $ — $ — $ — $ — $ 250 Contingent consideration $ 820 $ — $ — $ — $ — $ 820 Common stock warrant liability $ 15,801 $ 10,608 $ — $ — $ — $ 26,409

Debt Disclosure [Abstract]
Debt	8. DEBT On May 8, 2014, we refinanced our outstanding indebtedness under the prior facility and discharged our obligations thereunder by entering into a credit agreement (Credit Agreement) with a syndicate of lenders. The Credit Agreement currently provides for term loans in an aggregate principal amount of $350.0 million, which mature in May 2021 (Term Loans) and a revolving credit facility of $130.0 million, which matures in May 2019 (Revolving Facility). The effective interest rate on our Term Loans was 4.5% as of January 1, 2016. We also pay a quarterly unused line fee for the Revolving Facility in the range of 0.25% to 0.375% (based on our total net leverage ratio being within certain defined ranges) as well as overall agency fees. As of January 1, 2016, we had no borrowings under the Revolving Facility.

During development, IPR&D is not subject to amortization and is tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test consists of a comparison of the fair value to its carrying amount. If the carrying value exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. Once an IPR&D project is complete, it becomes a definite long-lived intangible asset and is evaluated for impairment in accordance with our policy for long-lived assets. Accumulated amortization for acquired technology and customer relationships was $58.1 million and $27.9 million, respectively, as of January 1, 2016, and $33.1 million and $8.6 million, respectively, as of January 2, 2015. In July 2013, we entered into a long term technology licensing and transfer agreement that calls for potential payments by us of up to $9.0 million through July 2016, based upon the achievement of specified milestones. Costs incurred in connection with the licensing and the transfer of the technology aggregated $9.6 million and $7.0 million as of January 1, 2016 and January 2, 2015, respectively, and were capitalized as incurred as acquired technology. Costs will be amortized to cost of revenue upon completion of the transfer, which is currently expected to be completed in fiscal year 2017.

Restructuring and Related Activities [Abstract]
Restructurings	13. RESTRUCTURINGS We have periodically implemented restructuring actions in connection with broader plans to reduce staffing, reduce our internal manufacturing footprint and, generally, reduce operating costs. The restructuring expenses are primarily comprised of direct and incremental costs related to headcount reductions including severance and outplacement fees for the terminated employees, as well as facility close costs. The following is a summary of the costs incurred and remaining balances included in accrued expenses for the three months ended January 1, 2016 (in thousands): Balance as of October 2, 2015 $ 943 Current period adjustments 157 Payments (357 ) Balance as of January 1, 2016 $ 743 The restructuring expenses recorded to date are expected to be paid through the remainder of fiscal year 2016. Our restructuring charges incurred to date are primarily employee related with non-employee related charges determined to be immaterial. We expect to incur additional restructuring costs of approximately $5.0 million to $7.0 million during the remainder of calendar year 2016 as we complete restructuring actions associated with the Metelics Acquisition.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Share - Based Compensation	14. SHARE-BASED COMPENSATION Stock Plans As of January 1, 2016, we had 8.7 million shares available for future issuance under our 2012 Omnibus Incentive Plan (the “2012 Plan”). Under the 2012 Plan, we have the ability to issue incentive stock options (ISOs), non-statutory stock options (NSOs), performance-based non-statutory stock options, stock appreciation rights, restricted stock (RSAs), restricted stock units (RSUs), performance-based stock units (PRSUs), performance shares, and other equity-based awards to employees, directors and outside consultants. Options granted to date primarily vest over a four-year period with 25% vesting at the end of one year and the remaining vesting monthly thereafter, and generally have a term of up to 10 years. Certain of the share-based awards granted and outstanding as of January 1, 2016 are subject to accelerated vesting upon a changes in control. The financial impact of any modifications to share-based awards during the periods presented was immaterial. As of January 1, 2016, total unrecognized compensation cost related to the employee stock purchase plan was not material. Stock Options We had 1.1 million stock options outstanding as of January 1, 2016, with a weighted-average exercise price per share of $22.56 and weighted-average remaining contractual term of 6.4 years. The aggregate intrinsic value of the stock options outstanding as of January 1, 2016 was $20.5 million which represents our closing stock price value on the last trading day of the period in excess of the weighted-average exercise price multiplied by the number of options outstanding. During the three months ended January 1, 2016, we granted 300,000 performance-based non-qualified stock options with a grant date fair value of $3.5 million that are subject to vesting only upon the market price of the Company’s underlying public stock closing above a certain price target within seven years of the date of grant. Due to the market condition upon which vesting is based, the fair value of the awards was estimated using a Monte Carlo simulation model. Compensation cost is recognized regardless of the number of awards that are earned based on the market condition. Compensation cost is recognized on a straight-line basis over the estimated service period of approximately three years. In the event that the Company’s common stock achieves the target price of $64.22 per share based on a 30 day trailing average prior to the end of the estimated service period, any remaining unamortized compensation cost will be recognized. The total intrinsic value of options at the time of exercise was $2.2 million and $0.8 million for the three months ended January 1, 2016 and January 2, 2015, respectively. Restricted Stock, Restricted Stock Units and Performance-Based Restricted Stock Units A summary of restricted stock, restricted stock unit and performance-based restricted stock unit activity for the three months ended January 1, 2016, is as follows (in thousands): Number of Weighted- Average Grate Date Aggregate Intrinsic Value Balance at October 2, 2015 1,692 $ 25.30 Granted 159 $ 32.60 Vested and released (26 ) $ 14.61 Forfeited, canceled or expired (11 ) $ 25.07 Balance at January 1, 2016 1,814 $ 26.10 $ 26,830 Restricted stock, restricted stock units and performance-based restricted stock units that vested during the three months ended January 1, 2016 and January 2, 2015 had fair value of $0.9 million and $0.9 million as of the vesting date, respectively. Share-Based Compensation The following table shows a summary of share-based compensation expense included in the Condensed Consolidated Statement of Operations for the three months ended January 1, 2016 and January 2, 2015 (in thousands): Three Months Ended January 1, January 2, Cost of revenue $ 457 $ 346 Research and development 1,837 962 Selling, general and administrative 5,088 1,851 Total stock-based compensation expense $ 7,382 $ 3,159 As of January 1, 2016, the total unrecognized compensation costs related to outstanding stock options and RSUs expected to vest was $39.9 million, which we expect to recognize over a weighted-average period of 4.4 years.

Income Tax Disclosure [Abstract]
Income Taxes	15. INCOME TAXES We are subject to income tax in the United States as well as other tax jurisdictions in which we conduct business. Earnings from non-U.S. activities are subject to local country income tax and may also be subject to current U.S. income tax. For interim periods, we record a tax provision or benefit based upon the estimated effective tax rate expected for the full fiscal year, adjusted for material discrete taxation matters arising during the interim periods. The difference between the U.S. federal statutory income tax rate of 35% and our effective income tax rates for the three months ended January 1, 2016 and January 2, 2015, was primarily impacted in all periods by changes in fair values of the common stock warrant liability which is neither deductible nor taxable for tax purposes, income taxed in foreign jurisdictions at generally lower tax rates, non-deductible compensation, research and development tax credits and non-deductible merger expenses, offset by U.S. state income taxes. The balance of the unrecognized tax benefit for the three months ending January 1, 2016 did not change and remained at $1.7 million. The unrecognized tax benefits primarily relate to positions taken by us in our 2014 US tax filings. The entire balance of unrecognized tax benefits, if recognized, will reduce income tax expense. It is our policy to recognize any interest and penalties accrued related to unrecognized tax benefits in income tax expense. During the quarter ending January 1, 2016, we did not make any payment of interest and penalties. As disclosed in Note 2 - Acquisitions
