Basis of Presentation [Abstract]
Basis of Presentation	1.  Basis of Presentation
	Interim financial statements and information are unaudited; however, in the opinion of management, all adjustments necessary for a fair and accurate presentation of the interim results in conformity with U.S. generally accepted accounting principles (“GAAP”) have been made.  All such adjustments were of a normal recurring nature.  The results for the three and nine month periods ended March 29, 2015 are not necessarily an indication of results to be expected for the entire fiscal year.  All information reported in this Form 10-Q should be read in conjunction with the Company’s annual consolidated financial statements for the fiscal year ended June 29, 2014 included in the Company’s Annual Report on Form 10-K.  The accompanying balance sheet at June 29, 2014 has been derived from those audited financial statements.  Because the Company is viewed as a single operating segment for management purposes, no segment information has been disclosed.
	Revenue Recognition
	The Company recognizes revenues when the earnings process is complete, when persuasive evidence of an arrangement exists, the product has been delivered, the price is fixed and determinable and collection is reasonably assured.  For the quarter and nine months ended March 29, 2015, the Company recognized approximately 16% and 15%, respectively, of net revenues from domestic distributors that are recognized under agreements which provide for certain sales price rebates and limited product return privileges.  Given the uncertainties associated with the levels of pricing rebates, the ultimate sales price on domestic distributor revenue transactions is not fixed or determinable until domestic distributors sell the merchandise to the end-customer.  At the time of shipment to domestic distributors, the Company records a trade receivable and deferred revenue at the distributor purchasing price since there is a legally enforceable obligation from the distributor to pay for the products delivered.  The Company relieves inventory as title has passed to the distributor and recognizes deferred cost of sales in the same amount. “Deferred income on shipments to distributors” represents the difference between deferred revenue and deferred cost of sales and is recognized as a current liability until such time as the distributor confirms a final sale to its end customer.  At March 29, 2015, the Company had approximately $59.6 million of deferred revenue and $12.0 million of deferred cost of sales recognized as $47.6 million of “Deferred income on shipments to distributors.”  The Company believes that its deferred costs of revenues have limited risk of material impairment as the Company offers stock rotation privileges to distributors (up to 3% to 5% of quarterly purchases) which enable distributors to rotate slow moving inventory. In addition, stock rotated inventory that is returned to the Company is generally resalable.  The Company reviews distributor ending on-hand inventory balances, as well as orders placed on the Company to ensure that distributors are not overstocking parts and are ordering to forecasted demand. To the extent the Company had a significant reduction in distributor price or grants significant price rebates, there could be a material impact on the ultimate revenue and gross profit recognized. The price rebates that have been remitted back to distributors have generally ranged from $3.5 million to $4.4 million per quarter.
	The Company’s sales to international distributors are made under agreements which permit limited stock return privileges but not sales price rebates.  Revenue on these sales is recognized upon shipment at which time title passes.  The Company has reserves to cover expected product returns.  If product returns for a particular fiscal period exceed or are below expectations, the Company may determine that additional or less sales return allowances are required to properly reflect its estimated exposure for product returns.  Generally, changes to sales return allowances have not had a significant impact on operating margin.

Earnings Per Share [Abstract]
Earnings Per Share	3. Earnings Per Share
	Basic earnings per share is calculated using the weighted average shares of common stock (including unvested restricted stock) outstanding during the period.  Diluted earnings per share is calculated using the weighted average shares of common stock outstanding, the dilutive effect of stock options and restricted stock units, calculated using the treasury stock method and the dilutive effect of the conversion premium related to the Convertible Senior Notes.  The following table sets forth the reconciliation of weighted average common shares outstanding used in the computation of basic and diluted earnings per share:

	For the quarter and nine months ended March 29, 2015, there were no out-of-the-money stock options that had to be excluded from the weighted average diluted common shares outstanding.  There was no dilutive effect from the conversion premium in the calculation of diluted earnings per common shares for the current fiscal year as a result of the conversion of the Convertible Senior Notes at the end of fiscal year 2014.
	For the quarter and the nine months ended March 30, 2014, there were no out-of-the-money stock options that had to be excluded from the weighted average diluted common shares outstanding. For the quarter and the nine months ended March 30, 2014, the Company included the dilutive effect from the conversion premium related to the convertible senior notes in the calculation of diluted earnings per common share because the average per share market price of the Company’s common stock was above the conversion price during the quarter.

Fair Value [Abstract]
Fair Value	4.Fair Value
	The Company has determined that the only assets and liabilities in the Company’s financial statements that are required to be measured at fair value on a recurring basis are the Company’s investment portfolio assets.  Financial instruments are categorized in a fair value hierarchy that prioritizes the information used to develop assumptions for measuring fair value and expands disclosures about fair value measurements. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1 input); then to quoted prices (in non-active markets or in active markets for similar assets or liabilities), inputs other than quoted prices that are observable for the asset or liability, and inputs that are not directly observable, but that are corroborated by observable market data for the asset or liability (Level 2 input); then the lowest priority to unobservable inputs, for example, the Company’s data about the assumptions that market participants would use in pricing an asset or liability (Level 3 input). Fair value is a market-based measurement, not an entity-specific measurement, and a fair value measurement should therefore be based on the assumptions that market participants would use in pricing the asset or liability.
	The Company’s Level 1 assets consist of investments in money-market funds and United States Treasury securities that are actively traded.  The Company’s Level 2 assets consist of municipal bonds, obligations of U.S. government-sponsored enterprises, corporate debt and commercial paper that are less actively traded in the market, but where quoted market prices exist for similar instruments that are actively traded. The Company determines the fair value of its Level 2 assets by obtaining non-binding market prices from its third-party portfolio managers on the last day of the quarter. The Company has no Level 3 assets.
	The following table presents the Company’s fair value hierarchy for its financial assets (cash equivalents and marketable securities) measured at fair value on a recurring basis as of March 29, 2015:

	(1) The Company evaluated the nature of the investments with a loss position at March 29, 2015 and June 29, 2014, which are primarily obligations of the U.S. government and its sponsored enterprises, municipal bonds and U.S. corporate notes.  In evaluating the investments, the Company considered the duration of the impairments, and the amount of the impairments relative to the underlying portfolio and concluded that such amounts were not other-than-temporary. The Company principally holds securities until maturity, however, they may be sold under certain circumstances.  Unrealized losses on the investments greater than twelve months old were not significant as of March 29, 2015 and June 29, 2014.
	The estimated fair value of debt investments in marketable securities, by effective maturity date is as follows:

Stock-Based Compensation	6.    Stock-based Compensation
	Equity Incentive Plans
	At March 29, 2015, 20.4 million shares were available for grant under the Company’s equity incentive plans.  The Company’s restricted awards generally vest annually over a period of five years (20% a year) based upon continued employment with the Company.  Options vest over a five-year period (generally 10% every six months) based upon continued employment.   Options expire seven years after the date of the grant. The Company's last stock option grant to an employee was in January 2009.
	The Company has an Employee Stock Purchase Plan (“ESPP”) that permits eligible employees to purchase common stock through payroll deductions at 85% of the fair market value of the common stock at the end of each six-month offering period.  The offering periods generally commence on approximately May 1 and November 1 of each year.  At March 29, 2015, 0.6 million shares were available for issuance under the ESPP.
	Accounting for Stock-Based Compensation
	Compensation cost for restricted stock awards is based on the fair market value of the Company’s stock on the date of grant.  Compensation cost for stock options is calculated on the date of grant using the fair value of stock options as determined using the Black-Scholes valuation model.  The Company amortizes the compensation cost straight-line over the vesting period, which is generally five years.  The Black-Scholes valuation model requires the Company to estimate key assumptions such as expected option term, stock price volatility and forfeiture rates to determine the fair value of a stock option. The estimate of these key assumptions is based on historical information and judgment regarding market factors and trends.
	As of March 29, 2015, there was approximately $184.4 million of total unrecognized stock-based compensation cost related to share-based payments granted under the Company’s stock-based compensation plans that will be recognized over a period of approximately 5 years.  Future grants will add to this total, whereas quarterly amortization and the vesting of the existing grants will reduce this total.
	The Company issues new shares of common stock upon exercise of stock options. For the nine months ended March 29, 2015, options for approximately 0.9 million shares were exercised for a gain to the optionee (aggregate intrinsic value) of $21.2 million determined as of the dates of the option exercises.

	Goodwill
	The Company annually evaluates goodwill for impairment as well as whenever events or changes in circumstances might suggest that the carrying value of goodwill may not be recoverable.  The Company expects that none of the goodwill will be deductible for tax purposes.  The goodwill balance of $2.2 million at March 29, 2015 is attributable to the acquisition of Dust Networks ("Dust") in fiscal year 2012.  There have been no changes to the goodwill balance since the fiscal year ended June 29, 2014.
	Intangible Assets
	As a result of the acquisition of Dust during the second quarter of fiscal year 2012 the Company recorded intangible assets consisting of $13.1 million of intellectual property and $4.0 million of customer relationships. The Company reviews intangible assets for impairment whenever events or changes in circumstances indicate that the carrying value of assets may not be recoverable. Finite-intangible assets are amortized on a straight-line basis over their estimated useful lives that are expected to reflect the estimated pattern of economic use.
	The remaining amortization expense, related to finite-intangible assets, is being recognized over a weighted-average period of approximately 5.9 years.  The useful lives of amortizable intangible assets are as follows:
	Assets	Life
	Intellectual property	5-10 years
	Customer relationships	10 years
	Intangible assets consisted of the following:

Convertible Senior Notes [Abstract]
Convertible Senior Notes	9.Convertible Senior Notes
	During the fourth quarter of fiscal year 2007, the Company issued $1.0 billion aggregate principal amount of its 3.00% Convertible Senior Notes due May 1, 2027 (the “2027A notes”) and $700.0 million aggregate principal amount of its 3.125% Convertible Senior Notes due May 1, 2027 (the “2027B notes” and, together with the 2027A notes, the “Notes”) to an initial purchaser in a private offering.  The Company received net proceeds from the issuance of the Notes of $1,678.0 million after the deduction of issuance costs of $22.0 million.  The Company used the entire net proceeds of the offering to fund a portion of its repurchase of $3.0 billion of its common stock pursuant to an accelerated stock repurchase transaction it entered into with an affiliate of the initial purchaser of the Notes simultaneously with the offering of the Notes.
	The Company redeemed for cash $395.8 million (the remaining principal amount) of its 2027B notes in fiscal 2011 using a portion of its existing cash and marketable securities balances.  On May 1, 2014 the Company executed the conversion of the remaining principal amount of $845.1 million of its 2027A notes.  On such date, each $1,000 principal amount of the 2027A notes was convertible at a rate of 24.582 shares (which is equivalent to a conversion price of approximately $40.68 per share) of the Company’s common stock.  The first $1,000 in conversion value of $845.1 million was paid in cash and the remaining conversion premium of $138.9 million was settled in common stock, as provided in the Indenture for the 2027A Notes. As a result of the conversion, holders of the 2027A notes received the principal amount of $845.1 million in cash and the remaining conversion premium was settled in shares of the Company’s common stock totaling approximately 2.9 million shares.  There was no gain or loss recognized as a result of the conversion.
	The 2027A notes paid cash interest of 3.00% semiannually in arrears on May 1 and November 1.  In accordance with the provisions of ASC 470-20-10 to 35, the Company recognized an effective interest rate of 5.69% on the carrying value of the 2027A notes. The effective rate was based on the interest rates of similar instruments issued at the time of issuance of the 2027A notes that did not have conversion features such as the 2027A notes.  The difference between the effective interest rate of 5.69% and the coupon rate of 3.00%, resulted in non-cash interest expense.
	Prior to the conversion, interest expense related to the Notes included in interest expense on the consolidated statements of income for the quarter and the nine months ended March 30, 2014 was as follows:

Credit Facility	10. Credit Facility
	On October 23, 2013, the Company entered into a Credit Agreement (the “Credit Agreement”) with Wells Fargo Bank, National Association (the “Bank”) to enhance cash deployment flexibility.
	The Credit Agreement provides for a $100.0 million unsecured revolving line of credit, under which the Company may borrow, repay and reborrow loans from time to time prior to its scheduled maturity date of October 22, 2015 (the “Maturity Date”).  Proceeds of loans made under the Credit Agreement may be used for working capital and other general corporate purposes of the Company and its subsidiaries.  The Company may prepay the loans under the Credit Agreement in whole or in part at any time without premium or penalty, subject to customary breakage costs.
	The loans bear interest at LIBOR plus 1.0%.  The principal amount, together with all accrued and unpaid interest, is due and payable on the Maturity Date.
	The Company is required to maintain with the Bank average account balances, calculated on a quarterly basis, of not less than $30.0 million.  The Company must also maintain EBITDA of not less than $75.0 million measured quarterly, and, in order to take certain actions such as payments of dividends, must also maintain a balance of $500.0 million of cash and cash equivalents and marketable securities on a worldwide consolidated basis.  The Credit Agreement contains other customary affirmative and negative covenants, as well as customary events of default.  Presently, the Company has not utilized the Credit Agreement.

	Stock Repurchase
	On October 14, 2014, the Company’s Board of Directors authorized the Company to purchase up to 10.0 million shares of its outstanding common stock in the open market over a two-year time period.  During the quarter ended March 29, 2015, the Company repurchased approximately 0.3 million shares of its common stock for approximately $14.7 million.
	In addition to open market repurchases, the Company also repurchases shares related to equity award vestings as outlined below. During the quarter ended March 29, 2015, the Company repurchased approximately 0.2 million shares related to equity grants of its common stock for approximately $8.5 million. The Company generally grants restricted stock awards and restricted stock units under its equity incentive plans, which are subject to vesting. Recipients are required to pay tax on such awards and units at the time they vest. For the majority of restricted stock awards and units granted, the number of shares issued on the date the awards and units vest is net of the minimum statutory withholding requirements that the Company pays in cash to the appropriate taxing authorities on behalf of its employees. These withheld shares are not included in the open market common stock repurchase totals in the above paragraph even though they are treated as common stock repurchases in our financial statements, as they reduce the number of shares that would otherwise have been issued.
	Dividends
	A cash dividend of $0.30 per share will be paid on May 27, 2015 to stockholders of record on May 15, 2015.   During the nine months ended March 29, 2015, the Company paid $205.0 million in dividends representing $0.84 per share.  The payment of future dividends will be based on the Company's financial performance.

	The Company’s warranty policy provides for the replacement of defective parts.  In certain large contracts, the Company has agreed to negotiate in good faith a product warranty in the event that an epidemic failure of its parts was to take place. To date there have been no significant occurrences.  Warranty expense historically has been negligible.
	The Company provides a limited indemnification for certain customers against intellectual property infringement claims related to the Company's products. In certain cases, there are limits on and exceptions to the Company's potential liability for indemnification relating to intellectual property infringement claims.  To date, the Company has not incurred any significant indemnification expenses relating to intellectual property infringement claims.  The Company cannot estimate the amount of potential future payments, if any, that it might be required to make as a result of these agreements, and accordingly, the Company has not accrued any amounts for its indemnification obligations.

	The Company must recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate resolution. As of March 29, 2015, the Company's other long-term liabilities account includes $30.1 million of unrecognized tax benefits of which approximately $11.4 million would favorably impact its effective income tax rate in future periods if the Company's positions on these tax matters are upheld.   The Company's policy is to recognize interest and/or penalties related to income tax matters in income tax expense. Included in the liability for unrecognized tax benefits was $1.9 million accrued for interest at March 29, 2015.

Revenue Recognition	Revenue Recognition
	The Company recognizes revenues when the earnings process is complete, when persuasive evidence of an arrangement exists, the product has been delivered, the price is fixed and determinable and collection is reasonably assured.  For the quarter and nine months ended March 29, 2015, the Company recognized approximately 16% and 15%, respectively, of net revenues from domestic distributors that are recognized under agreements which provide for certain sales price rebates and limited product return privileges.  Given the uncertainties associated with the levels of pricing rebates, the ultimate sales price on domestic distributor revenue transactions is not fixed or determinable until domestic distributors sell the merchandise to the end-customer.  At the time of shipment to domestic distributors, the Company records a trade receivable and deferred revenue at the distributor purchasing price since there is a legally enforceable obligation from the distributor to pay for the products delivered.  The Company relieves inventory as title has passed to the distributor and recognizes deferred cost of sales in the same amount. “Deferred income on shipments to distributors” represents the difference between deferred revenue and deferred cost of sales and is recognized as a current liability until such time as the distributor confirms a final sale to its end customer.  At March 29, 2015, the Company had approximately $59.6 million of deferred revenue and $12.0 million of deferred cost of sales recognized as $47.6 million of “Deferred income on shipments to distributors.”  The Company believes that its deferred costs of revenues have limited risk of material impairment as the Company offers stock rotation privileges to distributors (up to 3% to 5% of quarterly purchases) which enable distributors to rotate slow moving inventory. In addition, stock rotated inventory that is returned to the Company is generally resalable.  The Company reviews distributor ending on-hand inventory balances, as well as orders placed on the Company to ensure that distributors are not overstocking parts and are ordering to forecasted demand. To the extent the Company had a significant reduction in distributor price or grants significant price rebates, there could be a material impact on the ultimate revenue and gross profit recognized. The price rebates that have been remitted back to distributors have generally ranged from $3.5 million to $4.4 million per quarter.
	The Company’s sales to international distributors are made under agreements which permit limited stock return privileges but not sales price rebates.  Revenue on these sales is recognized upon shipment at which time title passes.  The Company has reserves to cover expected product returns.  If product returns for a particular fiscal period exceed or are below expectations, the Company may determine that additional or less sales return allowances are required to properly reflect its estimated exposure for product returns.  Generally, changes to sales return allowances have not had a significant impact on operating margin.
