	Equity Incentive Plans

	In May 2008, the Company’s stockholders approved the 2008 Equity Incentive Plan (“2008 Plan”). The 2008 Plan was amended by the Company’s stockholders in May 2010 to increase the number of shares reserved for issuance under the Plan by 1,500,000 shares. In May 2011, the 2008 Plan was amended again by the Company’s stockholders to increase the number of shares reserved for issuance under the Plan by 2,300,000 shares. Under the 2008 Plan, there is currently authorized for issuance and available for awards an aggregate of 5,000,000 shares of the Company’s common stock, plus up to an additional 2,407,369 shares that otherwise would have reverted to the share reserve of the Company’s prior incentive plan, the Company’s 1999 Stock Incentive Plan, subject to an overall, aggregate share reserve limit of 7,407,369 shares. Awards under the 2008 Plan may include stock options, restricted stock, stock appreciation rights, performance awards, restricted stock units and other awards, provided that with respect to full value awards, such as restricted stock or restricted stock units, no more than 300,000 shares may be issued in the form of full value awards during the term of the 2008 Plan. Awards under the 2008 Plan may be made to the Company’s officers and other employees, its board members and consultants that it hires. Generally, options vest over a four-year period and expire no more than seven years after the date of grant. The 2008 Plan has a term of ten years.

	Employee Stock Ownership Plan

	In January 2009, the Company established the PLX Technology, Inc. Employee Stock Ownership Plan (the “ESOP”). The ESOP is a non-leveraged, tax-qualified defined contribution retirement plan that is non-contributory. PLX regular employees (other than nonresident aliens with no U.S.-source income, employees covered by a collective bargaining agreement, leased employees and employees of a non-participating subsidiary of PLX) who are at least 18 years old and have worked for PLX for at least 12 consecutive months are eligible to participate in the ESOP. The Company makes cash contributions equal to a percentage of eligible compensation that is determined annually by the Board of Directors. Compensation costs are recorded based on the cash contribution amounts. Eligible compensation was limited to $150,000. The contributions are used to purchase common stock of the Company. Since the adoption of the ESOP, the Company has made annual contributions of 2% of each employee's eligible compensation up to a maximum of $3,000 for any single employee (2% of $150,000 of eligible compensation). In accordance with the IDT merger agreement, which was subsequently terminated, the Company ceased contributing to the plan after the April 2012 contribution. The reinstatement of contributions was approved by the Company’s Board of Directors effective as of the first quarter of 2013. Eligible participants received a share allocation at the end of the plan year based on the contributions plus an additional allocation for forfeitures that occurred during the plan year. The shares and forfeitures are allocated to each ESOP participant who is employed on the last day of the ESOP Plan Year (December 31) in the same proportion that the compensation (up to the $150,000 limit) of each ESOP participant bears to the eligible compensation of all ESOP participants.

	Share-Based Compensation Expense

	The fair value of share-based awards to employees is calculated using the Black-Scholes option pricing model, which requires subjective assumptions, including future stock price volatility and expected time to exercise, which greatly affect the calculated values.

	The weighted-average fair value of share-based compensation to employees is based on the multiple option valuation approach. Forfeitures are estimated and it is assumed no dividends will be declared. The estimated fair value of share-based compensation awards to employees is amortized using the straight-line method over the vesting period of the options. The weighted-average fair value calculations are based on the following average assumptions:




			Years Ended December 31,
			2013			2012			2011
	Expected volatility			57.94%			62.90%			61.34%
	Expected life (in years)			4.34			4.35			4.32
	Risk-free interest rate			1.13%			0.68%			1.21%

	Risk-Free Interest Rate. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the option.

	Expected Life. The Company’s expected life represents the weighted-average period that the Company’s stock options are expected to be outstanding. The expected life is based on the observed and expected time to post-vesting exercise of options by employees. The Company uses historical exercise patterns of previously granted options in relation to stock price movements to derive an employee behavioral pattern used to forecast expected exercise patterns.

	Expected Volatility. The Company believes that historical volatility best represents expected volatility due to the lack of market data consistently available to calculate implied volatility. The historical volatility is based on the weekly closing prices of its common stock over a period equal to the expected term of the option and is a strong indicator of the expected future volatility.

	These factors could change in the future, which would affect the share-based compensation expense in future periods.

	As share-based compensation expense recognized in the Consolidated Statements of Operations for the fiscal years 2013, 2012 and 2011 is based on awards ultimately expected to vest, it has been reduced for estimated forfeitures. Forfeitures are estimated based on historical experience at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

	The following table shows total share-based compensation and employee stock ownership plan expenses recorded for the years ended December 31, 2013, 2012 and 2011 (in thousands):




			Years Ended December 31,

	Total share-based compensation expense		$	2,698		$	3,144		$	2,330

	(1) Recorded in loss from discontinued operations in the Consolidated Statement of Operations.

	Share-based compensation expense from employee stock options and restricted stock units (“RSUs”) was $2.4 million, $3.0 million and $1.9 million for the years ended December 31, 2013, 2012 and 2011, respectively. For the same periods, ESOP expenses were $0.3 million, $0.2 million and $0.5 million, respectively.

	3. Net Income (Loss) Per Share

	The Company uses the treasury stock method to calculate the weighted-average shares used in the diluted earnings per. The following table sets forth the computation of basic and diluted net income (loss) per share (in thousands, except per share data):




		Years Ended December 31,
		2013		2012		2011

	Income (loss) from continuing operations	$	7,136	$	-5,201	$	3,104

	Weighted average shares outstanding - basic		45,603		44,882		44,559
	Dilutive effect of stock options and RSUs		920		-		457
	Weighted average shares outstanding - diluted		46,523		44,882		45,016

	Basic income (loss) per share from continuing operations	$	0.16	$	-0.12	$	0.07
	Diluted income (loss) per share from continuing operations	$	0.15	$	-0.12	$	0.07

	Weighted average employee stock options to purchase approximately 1.2 million shares for the year ended December 31, 2013, were outstanding, but were not included in the computation of diluted earnings per share as the exercise price of the options was greater than the average share price of the Company’s stock or the number of shares assumed to be repurchased using the proceeds of unrecognized compensation expense and exercise prices was greater than the weighted average number of shares underlying outstanding option and, therefore, the effect would have been anti-dilutive.

	As the Company incurred a loss from continuing operations for the year ended December 31, 2012, the effect of dilutive securities, totaling 4.5 million has been excluded from the computation of diluted loss per share, as their impact would be anti-dilutive. Dilutive securities are comprised of options to purchase common stock and RSUs.

	Weighted average employee stock options to purchase approximately 3.4 million for the year ended December 31, 2011, were outstanding, but were not included in the computation of diluted earnings per share as the exercise price of the options was greater than the average share price of the Company’s stock and, therefore, the effect would have been anti-dilutive.

	Total		$	7,375		$	1,809		$	3,966		$	1,600



	The fair value of the Company’s money-market funds classified as Level 1 is valued using prices in active markets. The fair values of the Company’s investments classified as Level 2 are valued using inputs that include actual trade data, benchmark yields, broker/dealer quotes and other similar data. These inputs are obtained from quoted market prices, independent pricing vendors or other sources.

	As of December 31, 2013, there were no assets requiring Level 3 measurements. The estimated fair value of the escrow payment was based on assumptions made regarding potential claims against the escrow using historical and market data and a 3.25% discount rate to consider present value. The Company estimated a claims rate of 17%. The escrow payment was received in November 2013. See Note 7 of the consolidated financial statements for more information on the escrow receivable.



	Investments

	As of December 31, 2013, the Company’s securities consisted of certificates of deposits and debt securities and were designated as available-for-sale. Available-for-sale securities are carried at fair value, based on quoted market prices or prices quoted in markets that are not active, with unrealized gains and losses reported in a separate component of stockholders’ equity. The amortized cost of debt securities is adjusted for the amortization of premiums and the accretion of discounts to maturity, both of which are included in interest income. Realized gains and losses are recorded on the specific identification method.

	The fair value of available-for-sale investments is as follows (in thousands):



			31-Dec-13

As of December 31, 2012, the Company had an aggregate unrealized loss of less than $1,000.

The Company reviews its available for sale investments for impairment at the end of each period. Investments in debt securities are considered impaired when the fair value of the debt security is below its amortized cost. If an impairment exists and the Company determines it has intent to sell the debt security or if it is more likely than not that it will be required to sell the debt security before recovery of its amortized cost basis, an other-than-temporary impairment loss is recognized in earnings to write the debt security down to its fair value. However, even if the Company does not expect to sell the debt security, it must evaluate expected cash flows to be received and determine if a credit loss exists. In the event of a credit loss, only the amount of impairment associated with the credit loss is recognized in earnings. Amounts relating to factors other than credit losses are recognized in other comprehensive income (loss). The Company did not record any other-than-temporary write-downs in the accompanying financial statements.

	5. Concentrations of Credit, Customer and Supplier Risk

	Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash equivalents, short-term investments, long-term investments and trade receivables. The Company generally invests its excess cash in money market funds, certificates of deposits, corporate bonds with high credit ratings, municipal bonds and treasury bills. The Company’s cash, cash equivalents, short and long-term investments were approximately $20.4 million as of December 31, 2013 which exceeded the amount insured by the Federal Deposit Insurance Corporation (“FDIC”). The Company has not experienced any significant losses on its cash equivalents or short and long-term investments.

	The Company performs ongoing credit evaluations of its customers and generally requires no collateral. Customers who accounted for 10% or more of net accounts receivable are as follows:




		December 31,
		2013		2012		2011

	Excelpoint Systems Pte Ltd.		26%		30%		27%
	Answer Technology, Inc.		21%		19%		12%
	Avnet, Inc.		*		21%		28%

	* Less than 10%



	The Company analyzes the need for reserves for potential credit losses and records reserves when necessary. Through fiscal 2013, there were no direct end customers that accounted for more than 10% of net revenues. Sales to the following distributors accounted for 10% or more of net revenues:




		Years Ended December 31,

	Avnet, Inc.		23%		24%		24%
	Answer Technology, Inc.		12%		19%		18%

	Currently, the Company relies on single source suppliers for the significant majority of its product inventory. As a result, should the Company's current suppliers not produce and deliver inventory for the Company to sell on a timely basis, operating results may be adversely impacted.

	6. UK Design Team Divestiture

	On October 5, 2011 the Company entered into an Asset Purchase agreement and IP license with OCZ Technology Group (OCZ) for $2.2 million in cash, whereby OCZ acquired the Company’s UK design team and related assets and liabilities, and obtained a nonexclusive perpetual license of its consumer storage technology. The deal closed on October 21, 2011. The Company continues to offer and support its current consumer storage products.

	Ralph Schmitt, PLX’s CEO in 2011, was also a member of OCZ’s board of directors. Throughout the term of negotiations and up to the date of acquisition of assets, he removed himself from all discussions to ensure execution of an arms-length transaction and had no authority to make decisions or influence the outcome of the arrangement.

	The Company recorded $1.7 million as license revenue and $0.5 million was allocated to sale of assets and the transfer of the UK design team and related liabilities based on the relative fair values. The carrying value of net assets transferred and goodwill allocated was $0.4 million and $74,000, respectively. Based on the carrying values of assets transferred, the Company recognized a gain of $28,000 on the divestiture.

	As a result of this divestiture, the Company also reviewed the useful life and amortization method of its storage acquired finite lived core technology intangible and determined that a change in the assets useful life and amortization method was required. The Company reduced the total estimated useful life of the intangible from five years to four years and changed the amortization method from straight line to an accelerated method that more closely matches the remaining cash inflows from the consumer storage products. The change in estimated life and amortization acceleration was reflected in the fourth quarter of 2011, the period of change.

	On September 20, 2012, the Company completed the sale of its physical layer 10GBase-T integrated circuit (“PHY”) family of products pursuant to an Asset Purchase Agreement (the “Aquantia APA”) between the Company and Aquantia Corporation for $2.0 million in cash.

	On July 6, 2012, the Company had also entered into an Asset Purchase Agreement (the “Entropic APA”) with Entropic Communications, Inc., pursuant to which the Company completed the sale of its digital channel stacking switch product line within the PHY product family, including certain assets exclusively related to the product line. Under the terms of the Entropic APA, the Company continued to have an obligation to complete the development in process. The agreement provided for $3.0 million upon closing and up to $5.0 million in future payments. Future payments consisted of a milestone payment of $2.0 million in connection with product acceptance, a $2.0 million escrow payment relating to certain representations, warranties and indemnities made by PLX and is due to be released to PLX twelve months after product acceptance and a $1.0 million milestone payment in the event a third party royalty arrangement is secured. In conjunction with the Entropic APA, the Company entered into an Intellectual Property License Agreement (the “License Agreement”) with Entropic which provided a fully paid, non-exclusive, royalty free license to certain of the physical layer 10GBase-T integrated circuit technology and provided for a $4.0 million payment from Entropic to the Company upon signing. In connection with the transaction with Aquantia, on November 21, 2012, the Company negotiated a modification to the Agreement with Entropic that amended and restated the product acceptance milestone such that the milestone was deemed to have occurred upon execution of the amendment and changed the associated consideration from $2.0 million to $1.4 million. In exchange, the obligation of PLX to complete the development of the product was assumed by Entropic.

	The consideration received for the combined sale of the PHY business totaled $12.0 million and consisted of cash received at closing in connection with the Aquantia APA of $2.0 million, the Entropic APA of $3.0 million, the License Agreement of $4.0 million, the accelerated product acceptance milestone payment of $1.4 million and the rights to the estimated fair value of the escrow payment under the Entropic APA of $1.6 million. The estimated fair value of the escrow payment was included in the Company’s balance sheet as other current assets as of December 31, 2012 and was based on assumptions made regarding potential claims against the escrow using historical and market data. The escrow payment was received for the full $2.0 million in November 2013 and $0.3 million was recorded as a gain for 2013. Future payments of up to $1.0 million which is contingent on future milestone achievements were not included in the consideration recorded and will be accounted for when they are probable of being received. The Company recorded a gain of $0.3 million and $3.5 million in 2013 and 2012, respectively, related to this divestiture.

	In June 2012 the Company recorded impairment charges of $10.3 million related to its 10 Gigabit Ethernet business, including core technology of $9.6 million, trade name and customer relationships of $0.2 million and certain tangible assets of $0.5 million. The primary factors contributing to this impairment charge was the uncertainty of and reduction in forecasted cash flows, resulting in an increase in the probability that the product line will be sold or disposed of based on the reduction and timing of future cash flows. In determining the amount of impairment charges the Company calculated the fair value of the asset group as of the impairment date. The valuation of the assets was classified as a level 3 measurement under the fair value measurement guidance. The fair value was determined using the weighted average of a discounted cash flow analysis and a market approach along with proceeds received from Entropic in July 2012 in connection with the IP license agreement. The discounted cash flow approach calculates the value based on the risk-adjusted present value of the cash flows related to 10 Gigabit Ethernet while the market approach calculates the value based on indications of what a market participant would pay for the asset group. The key unobservable inputs utilized in the discounted cash flow model include a 40% discount rate, a tax rate of 40% and future cash flows based on current product and market data. The impairment was recorded in discontinued operations in the Company’s Consolidated Statement of Operations in 2012.

	The acquisition of Teranetics and Oxford included the acquisition of $30.5 million and $9.1 million, respectively, of identifiable intangible assets. All of these intangibles were subject to amortization. There is no estimated residual value on any of the intangible assets. As of December 31, 2012 all acquired intangibles were fully amortized. There was no amortization expense in 2013.

	As of the result of the divestiture of the UK design team on October 21, 2011, the Company reviewed the useful life of its storage acquired intangibles and determined a change in the assets useful life and method of amortization was required. The Company reduced the useful life of the intangible from five years to four years and changed the amortization method from straight-line to an accelerated method. The change and amortization acceleration was reflected in the fourth quarter of 2011, the period of change.

	The amortization expense was $0.2 million and $2.8 million for the years ended December 31, 2012 and 2011, respectively.

	The amortization expense from discontinued operations was $5.1 million and $7.8 million for the years ended December 31, 2012 and 2011, respectively. In the second quarter of 2012, the Company recorded impairment charges of $9.8 million related to its core technology, trade name and customer relationships acquired in the Teranetics acquisition. See Note 9 of the consolidated financial statements for more information on the impairment. As a result of the impairment and the Entropic and Aquantia transactions, the Company reduced the remaining useful lives and accelerated the amortization of the Teranetics acquired intangibles. The remaining value of the intangibles of $5.8 million was written off and included in the gain on disposal in 2012. See Note 7 of the consolidated financial statements for more information on the divestiture of the PHY business.

	The Company sponsors the PLX Technology, Inc. 401(k) Plan (the “Plan”). The Plan allows all full-time employees to contribute up to 100% of their annual compensation. However, employee contributions are limited to a maximum annual amount established by the Internal Revenue Service. Beginning in 1996, the Company made a matching contribution calculated at 50 cents on each dollar of the first 6% of the participant’s compensation. The Company's expenses relating to the plan were approximately $0.4 million, $0.4 million and $0.4 million for 2013, 2012 and 2011, respectively.

	In January 2009, the Company established the PLX Technology, Inc. Employee Stock Ownership Plan (the “ESOP”). The ESOP is non-contributory and provides cash contribution at a percent of eligible U.S. compensation that is determined annually by the Board of Directors. The Company contributes 2% of eligible compensation up to $3,000 per employee. In accordance with the IDT merger agreement, which was subsequently terminated, the Company ceased contributing to the plan after the April 2012 contribution. The reinstatement of contributions was approved by the Company’s Board of Directors effective as of the first quarter of 2013. The expense recorded for contributions to this plan was approximately $0.3 million, $0.1 million and $0.3 million for 2013, 2012 and 2011, respectively.

	During the year ended December 31, 2013, the Company’s deferred tax asset valuation allowance increased by $0.2 million. The Company’s deferred tax asset valuation allowance decreased by $3.5 million in 2012 and increased by $11.2 million in 2011. The increase from December 31, 2012 to December 31, 2013 relates to the deferred tax assets generated primarily related to the true up of NOL carryforwards. The decrease from December 31, 2011 to December 31, 2012 relates to the sale of the PHY business and the unrealizability of the Teranetics tax attributes.

At December 31, 2013, the Company had federal and state net operating loss carryforwards of $81.6 million and $47.5 million, respectively. Net operating loss carryforwards will expire at various dates through 2032. During the fourth quarter of 2010, the Company concluded its analysis under Internal Revenue Code Section 382 for federal net operating losses and determined that utilization of the net operating loss and credit carryforwards are subject to various annual limitations. In addition, as of December 31, 2013, the Company had federal and state tax credit carryforwards of approximately $12.0 million and $17.8 million, respectively. The federal research and development credits will expire beginning in 2019 and the state credits will carryforward indefinitely. The Company also has approximately $25.7 million of net operating loss carryforwards from its UK operations.

Approximately $2.8 million of the federal and $2.1 million of the state net operating loss carryforward relate to excess tax deductions from stock options which have not yet been realized. The accounting guidance for share-based compensation prohibits recognition of a deferred income tax asset for excess tax benefits due to stock option exercises that have not yet been realized through a reduction in income tax payable.

Due to operating losses incurred, the Company created a full valuation allowance as of December 2002 for deferred tax assets. As of December 2013, a valuation allowance continues to be recorded for the net deferred tax asset based on management’s assessment that the realization of deferred tax assets is uncertain due to the history of losses, the variability of operating results and the inability to conclude that it is more likely than not that sufficient taxable income would be generated in future periods to realize those deferred tax assets. The Company will maintain a full valuation allowance until sufficient positive evidence exists to support a reversal of the valuation allowance. As of December 2013, the Company has a valuation allowance against net deferred assets of $67.2 million.

The Company intends to review on a quarterly basis the conclusions reached about the appropriate amount of its deferred income tax asset valuation allowance. We expect a significant benefit to be recorded in the period the valuation allowance reversal is recorded and a significantly higher effective tax rate in periods following the valuation allowance reversal.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is a follows (in thousands):




		Years Ended December 31,
		2013			2012			2011

Unrecognized tax benefits balance, beginning of period		$	5,429		$	4,401		$	4,038
Gross increase for tax positions for prior year			58			553			-
Gross increase for tax positions for current year			373			475			363
Unrecognized tax benefits balance, end of period		$	5,860		$	5,429		$	4,401

Future changes in the remaining balance of unrecognized tax benefits will have no impact on the effective tax rate as it is subject to a full valuation allowance.

The Company does not have any material accrued interest or penalties associated with any unrecognized tax benefits. The Company does not believe it is reasonably possible that its unrecognized tax benefits will significantly change within the next twelve months.

The Company is subject to taxation in the US and various state and foreign jurisdictions. The tax years 1999-2012 remain open to examination by the federal and state tax authorities. Net operating loss and tax credit carryforwards generated in prior periods remain open to examination.

The Company has made no provision for U.S. income taxes on approximately $0.7 million of cumulative undistributed earnings of certain foreign subsidiaries because it is the Company’s intention to indefinitely reinvest such earnings. If such earnings were distributed, the Company would accrue additional taxes of approximately $0.3 million. Foreign operations generated pre-tax profit of $2.2 million and $3.5 million in 2013 and 2012, respectively, and a pre-tax loss of $2.8 million in 2011.

	On September 30, 2011, the Company entered into an agreement with Silicon Valley Bank (SVB) to establish a two-year $10.0 million revolving loan facility. On April 22, 2013, the agreement was amended to increase the facility to $15.0 million and extend the maturity date to September 30, 2015. The facility provides for revolving advances based on a borrowing-base formula tied to the Company’s receivables and also provides for month-end and fiscal quarter-end advances beyond the borrowing-base formula subject to certain limitations and requirements. Borrowings under the credit facility bear interest at rates equal to the prime rate announced from time to time in The Wall Street Journal. As of December 31, 2013 the prime rate was 3.25%. The facility also provides for commitment, unused facility and letter-of-credit fees. The facility is secured by liens on the Company’s personal property assets except for intellectual property, which is subject to a negative pledge against encumbrance. As of December 31, 2013 there is $5.0 million outstanding against the facility. In addition, the Company issued an irrevocable letter of credit of $0.8 million against the facility for the bond issued as a result of the judgment in the Internet Machines litigation. Borrowing availability as of December 31, 2013 is $9.2 million. Interest payments are made monthly with principal due at maturity.

	The facility is subject to certain financial covenants for earnings before interest, taxes, depreciation and amortization (“EBITDA’), as defined in the agreement, and a monthly quick ratio computation (PLX’s cash, investments and accounts receivable divided by current liabilities). The Company was in compliance with all financial covenants associated with this facility as of December 31, 2013.

	Litigation

	To date, Internet Machines LLC ("Internet Machines") has filed three separate lawsuits against PLX. The first suit was filed on February 2, 2010, which has been served on PLX, entitled Internet Machines LLC v. Alienware Corporation, et al., in the United States District Court for the Eastern District of Texas, Tyler Division (the “First Suit”). This First Suit alleges infringement by PLX and the other defendants in the lawsuit of two patents held by Internet Machines. The complaint in the lawsuit seeks unspecified compensatory damages, treble damages and attorneys' fees, as well as injunctive relief against further infringement of Internet Machines' patents. On May 14, 2010, the Company filed its answer to the live complaint and asserted counterclaims, seeking declaratory judgments of non-infringement and invalidity of the patents-in-suit. On December 6, 2010, the Court held a case-management conference and subsequently entered a scheduling order in this matter, and set the trial for February 2012.

	On February 21, 2012, through February 29, 2012, the claims and defenses asserted in the First Suit were tried to a seven-member jury in the United States District Court for the Eastern District of Texas, Tyler Division. On February 29, 2012, the jury returned its verdict, finding the patents-in-suit valid and infringed and awarded money damages against PLX in the amount of $1.0 million. On June 19, 2013, the Court issued its ruling on the post-verdict motions filed by the parties and entered an appealable judgment, affirming the jury’s findings of validity and infringement. The judgment entered by the Court further affirmed the monetary award found by the jury. On July 17, 2013, the Company filed a notice of appeal with the Court and on October 7, 2013 it filed the appeal brief, appealing the judgment to the United States Court of Appeals for the Federal Circuit. The Company intends to continue to vigorously seek reversal of the jury’s verdict and the Court’s judgment on appeal.

	Internet Machines' second lawsuit, which has also been served on PLX, was filed on October 17, 2010, again in the United States District Court for the Eastern District of Texas, Tyler Division (the “Second Suit”). This Second Suit, entitled Internet Machines LLC v. ASUS Computer International, et al., alleges infringement by PLX of another patent held by Internet Machines. The complaint also asserts infringement claims against a separate group of defendants not named in the first Internet Machines lawsuit, and accuses those defendants of infringing the two patents asserted against PLX in the First Suit, as well as the additional patent listed in this Second Suit. The complaint in the lawsuit seeks unspecified compensatory damages, treble damages and attorneys' fees, as well as injunctive relief against further infringement of Internet Machines' patents. On December 28, 2010, the Company filed its answer to the live complaint in the second lawsuit and asserted counterclaims, seeking declaratory judgments of non-infringement and invalidity of the patents-in-suit.

	On May 17, 2011, Internet Machines filed a third lawsuit entitled Internet Machines LLC v. Avnet, Inc., et al., again in the United States District Court for the Eastern District of Texas, Tyler Division (the “Third Suit”). The third lawsuit has been served on PLX and alleges that PLX infringes a fourth patent held by Internet Machines. This lawsuit also accuses a new group of defendants of infringing each of Internet Machines' patents at issue in the First and Second Suits, as well as the fourth patent asserted against PLX in this Third Suit. The complaint in the Third Suit seeks unspecified compensatory damages, treble damages and attorneys' fees, as well as injunctive relief against further infringement of Internet Machines' patents. On September 27, 2011, the Company filed its answer to the live complaint and asserted counterclaims, seeking declaratory judgments of non-infringement and invalidity of the patents-in-suit.

	On January 20, 2012, the Court entered an order consolidating the Second and Third Suits into one action. The Court further ordered that the schedule entered in the Third Suit would govern the consolidated action. As a result, the consolidated action was originally set for trial in February 2013.

	On March 25, 2011, a related entity, Internet Machines MC LLC, filed a lawsuit against PLX, entitled Internet Machines MC LLC v. PLX Technology, Inc., et al., in the United States District Court for the Eastern District of Texas, Marshall Division. Internet Machines MC LLC, however, did not serve the initial complaint on PLX. Instead, on August 26, 2011, Internet Machines MC LLC filed a first amended complaint, which has now been served on PLX, alleging infringement by PLX and the other defendants in the lawsuit of one patent held by Internet Machines MC LLC. The complaint in this lawsuit seeks unspecified compensatory damages, treble damages and attorneys' fees, as well as injunctive relief against further infringement of Internet Machines MC LLC's patents. On November 11, 2011, the Company filed its answer to the live complaint and asserted counterclaims, seeking declaratory judgments of non-infringement and invalidity of the patents-in-suit. On March 5, 2012, the Court held an initial case-management conference in this matter. The Court entered a scheduling order in this matter, and trial was originally set for July 2013.

	On September 4, 2012, the Court entered an order staying the Second and Third Suits and the lawsuit brought by Internet Machines MC LLC discussed in the preceding paragraph. Pursuant to the Court’s order, those lawsuits are stayed until a final non-appealable judgment is entered in the First Suit, again styled Internet Machines LLC v. Alienware Corp., et al., Cause No. 6:10-CV-023, in the United States District Court for the Eastern District of Texas. While it is not possible to determine the ultimate outcome of these suits, the Company believes that it has meritorious defenses with respect to the claims asserted against it and intends to vigorously defend its position, but it is unable to estimate a range of possible loss, if any.

	As a result of the jury’s February 29, 2012 verdict on the First Suit, the Company accrued $1.0 million as of December 31, 2011. Based on the June 19, 2013 Court’s ruling, the Company accrued an additional $0.9 million. As noted above, the Company has filed an appeal of the jury’s verdict and the Court’s judgment issued in the First Suit. The Company will continue to accrue royalties, under the Court’s direction, until the appeal is finalized. A change in the ruling as a result of that appeal could change the estimated liability in the period in which the outcome of the appeal is known.

	From time to time, the Company is involved in claims and legal proceedings that arise in the ordinary course of business. Any claims or proceedings against the Company, whether meritorious or not, could be time consuming, result in costly litigation, require significant amounts of management time, result in the diversion of significant operational resources or require the Company to enter into royalty or licensing agreements which, if required, may not be available on terms favorable to the Company or at all. If management believes that a loss arising from these matters is probable and can be reasonably estimated, the Company will record a reserve for the loss.

	Warranty and Indemnification Provisions

	Changes in sales warranty reserve are as follows (in thousands):

	Warranty costs, which relate to product quality issues, remained consistent and insignificant during the periods presented.

	The Company enters into standard indemnification agreements with many of its customers and certain other business partners in the ordinary course of business. These agreements include provisions for indemnifying the customer against any claim brought by a third-party to the extent any such claim alleges that a PLX product infringes a patent, copyright or trademark, or violates any other proprietary rights of that third-party. It is not possible to estimate the maximum potential amount of future payments the Company could be required to make under these indemnification agreements. To date, the Company has not incurred any significant costs to defend lawsuits or settle claims related to these indemnification agreements. No liability for these indemnification agreements has been recorded at December 31, 2013, 2012 or 2011.

Organization And Summary Of Significant Accounting Policies [Abstract]	'
Basis Of Presentation	'
	Basis of Presentation

	The consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States and include the accounts of the Company and its wholly-owned subsidiaries in China, India, Japan, Korea, Singapore, Taiwan and the United Kingdom. All intercompany transactions and balances have been eliminated.



Cash And Cash Equivalents	'
	Cash and Cash Equivalents

	The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents.


Investments	'

	Investments

	At December 31, 2013, the Company’s securities consisted of certificates of deposits and debt securities. Management determines the appropriate classification of debt securities at the time of purchase and reevaluates such designation as of each balance sheet date. At December 31, 2013 and 2012, all debt securities were designated as available-for-sale. Available-for-sale securities are carried at fair value, based on quoted market prices or prices quoted in markets that are not active, with unrealized gains and losses reported in a separate component of stockholders' equity. The amortized cost of debt securities is adjusted for the amortization of premiums and the accretion of discounts to maturity both of which are included in interest income. Realized gains and losses are recorded on the specific identification method.

	The accounting guidance for fair value measurements provided a framework for measuring fair value and expands related disclosures. Fair value is defined as the price that would be received for an asset or the exit price that would be paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants on the measurement date. The guidance also established a hierarchy which requires an entity to maximize the use of observable inputs, when available. The guidance requires fair value measurement be classified and disclosed in one of the following three categories:

	Level 1: Valuations based on quoted prices in active markets for identical assets and liabilities. The fair value of available-for-sale securities included in the level 1 category is based on quoted prices that are readily and regularly available in an active market.

	Level 2: Valuations based on observable inputs (other than Level 1 prices), such as quoted prices for similar assets at the measurement date; quoted prices in markets that are not active; or other inputs that are observable, either directly or indirectly. The fair value of available-for-sale securities included in the Level 2 category is based upon quoted prices in markets that are not active and incorporate available trade, bid and other market information.

	Level 3: Valuations based on inputs that are unobservable and involve management judgment and the reporting entity’s own assumptions about market participants and pricing.


Accounts Receivable And Allowance For Doubtful Accounts	'
	Accounts Receivable and Allowance for Doubtful Accounts

	Accounts receivable are recorded at the invoiced amount and do not bear interest. The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in its existing accounts receivable. The Company determines the allowance based on historical write-off experience and customer economic data. The Company reviews its allowance for doubtful accounts monthly. Past due balances over 90 days are reviewed individually for collectability. Account balances are charged off against the allowance when the Company believes that it is probable the receivable will not be recovered.

Inventories	'
	Inventories

	Inventories are valued at the lower of cost (first-in, first-out method) or market (net realizable value). Inventories were as follows (in thousands):




		December 31,
		2013		2012
	Work-in-process	$	5,561	$	4,986
	Finished goods		4,728		5,574
	Total	$	10,289	$	10,560

	The Company evaluates the need for potential inventory write downs by considering a combination of factors, including the life of the product, sales history, obsolescence, sales forecasts and expected sales prices.

Goodwill	'
	Goodwill

	Goodwill represents the excess of cost over the value of net assets of businesses acquired and is carried at cost unless write-downs for impairment are required. The Company’s goodwill as of December 31, 2013, is a result of the Oxford and Teranetics acquisition on January 2, 2009 and October 1, 2010, respectively, as adjusted for the 2012 divestiture of the PHY business and the 2011 divestiture of the UK design team. The Company evaluates the carrying value of goodwill on an annual basis during the fourth quarter and whenever events and changes in circumstances indicate that the carrying amount may not be recoverable. Such indicators would include a significant reduction in the Company's market capitalization, a decrease in operating results or a deterioration in the Company's financial position. The Company operates under a single reporting unit, and accordingly, all of its goodwill is associated with the entire company. In the fourth quarter of 2013 and 2012, the Company tested the carrying value of goodwill and determined there was no impairment.

	Changes in the carrying amount of goodwill for the years ended December 31, 2013 and 2012 are as follows (in thousands):




		December 31,
		2013		2012
	Goodwill	$	55,153	$	56,030
	Accumulated impairment losses		-34,692		-34,692
	Net goodwill at beginning of period		20,461		21,338

	Goodwill adjustment for divestiture of PHY business		-		-877
	Net goodwill at end of period	$	20,461	$	20,461



Long-lived Asset Impairment	'
	Long-lived Asset Impairment

	Long-lived assets, principally property and equipment, held and used by the Company are reviewed for impairment whenever events or circumstances indicate that the carrying amount of assets may not be recoverable. The Company evaluates recoverability of assets to be held and used by comparing the carrying amount of an asset to estimated future net undiscounted cash flows generated by the asset. If such assets are considered to be impaired, the impairment recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets.

Property And Equipment	'
	Property and Equipment

	Property and equipment are stated at cost, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of thirty nine years for buildings, three to eight years for building improvements and three to seven years for equipment, furniture and purchased software.



	Property and equipment are as follows (in thousands):




		December 31,
		2013		2012
	Land	$	3,150	$	3,150
	Building and improvements		4,327		4,327
	Equipment and furniture		15,888		14,955
	Purchased software		2,401		2,371
			25,766		24,803
	Accumulated depreciation		-15,433		-13,536
	Net property and equipment	$	10,333	$	11,267

	Depreciation and amortization expense from continuing operations pertaining to property and equipment was approximately $2.0 million, $2.2 million and $2.4 million for the years ended December 31, 2013, 2012 and 2011, respectively.

Foreign Currency Translation	'
	Foreign Currency Translation

	The functional currency of the Company’s international subsidiaries in China, India, Japan, Korea Singapore, Taiwan and UK, is the local currency of the resident countries. Assets and liabilities of the Company’s foreign subsidiaries are translated into the Company’s reporting currency at month-end exchange rates. Revenues and expenses of the Company’s foreign subsidiaries are translated into the Company’s reporting currency at weighted-average exchange rates. The effects of the translation are included in a separate component of the Consolidated Statements of Stockholder’s Equity and Comprehensive Income (Loss).

Income Taxes	'
	Income Taxes

	Income taxes are accounted for using the asset and liability method. Under this method, deferred tax liabilities and assets are recognized for the expected future tax consequences of differences between the carrying amounts and the tax bases of assets and liabilities. A valuation allowance is provided when it is more likely than not that all or some portion of deferred tax assets will not be realized.

	The Company recognizes the tax liability for uncertain income tax positions on the income tax return based on the two-step process. The first step is to determine whether it is more likely than not that each income tax position would be sustained upon audit. The second step is to estimate and measure the tax benefit as the amount that has a greater than 50% likelihood of being realized upon ultimate settlement with the tax authority. Estimating these amounts requires the Company to determine the probability of various possible outcomes. The Company evaluates these uncertain tax positions on a quarterly basis. This evaluation is based on the consideration of several factors including changes in facts or circumstances, changes in applicable tax law, settlement of issues under audit and new exposures. If the Company later determines that the exposure is lower or that the liability is not sufficient to cover its revised expectations, the Company adjusts the liability and effect a related change in its tax provision during the period in which the Company makes such determination.

Revenue Recognition	'
	Revenue Recognition

	The Company recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable and collection is reasonably assured.

	Revenue from product sales to direct customers and distributors is recognized upon shipment and transfer of risk of loss, if the Company believes collection is reasonably assured and all other revenue recognition criteria are met. The Company assesses the probability of collection based on a number of factors, including past transaction history and the customer’s creditworthiness. At the end of each reporting period, the sufficiency of allowances is assessed based on the age of the receivable and the individual customer’s creditworthiness.

	The Company offers pricing protection to two distributors whereby the Company supports the distributor’s resale product margin on certain products held in the distributor’s inventory. The Company analyzes current requests for credit in process, also known as ship and debits, historical rates and amounts of credits issued and inventory at the distributor to determine the ending sales reserve required for this program. The Company also offers stock rotation rights to two distributors such that they can return up to a total of 5% of products purchased every six months in exchange for other PLX products of equal value. The Company analyzes current stock rotation requests, past experience and ending inventory to determine the ending sales reserve required for this program. As of December 31, 2013 and 2012, the Company had a reserve allowance for these programs of $1.8 million and $2.1 million, respectively. Provisions for reserves are charged directly against revenue and related reserves are recorded as a reduction to accounts receivable.

Product Warranty	'
	Product Warranty

	The Company sells products with a limited warranty of product quality for a period of one year, and up to three years for a small number of customers, and a limited indemnification of customers against intellectual property infringement claims related to the Company’s products. The Company accrues for known warranty and indemnification issues if a loss is probable and can be reasonably estimated, and accrues for estimated incurred but unidentified issues based on historical activity.

Use Of Estimates	'
	Use of Estimates

	The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates and such differences may be material to the consolidated financial statements.

Comprehensive Loss	'
	Comprehensive Income (Loss)

	The changes in the components of accumulated other comprehensive loss, net of tax, reflected in the Consolidated Statements of Stockholders' Equity and Comprehensive Income (Loss), consisted of the following (in thousands):

Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements

	In February 2013, the FASB issued amendments to the accounting guidance for presentation of comprehensive income to improve the reporting of reclassifications out of accumulated other comprehensive income. The amendments do not change the current requirements for reporting net income or other comprehensive income, but do require an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, an entity is required to present, either on the face of the statement where the net income is presented or in the notes, significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income but only if the amount reclassified is required under GAAP to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required under GAAP to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures required under GAAP that provide additional detail about these amounts. For public companies, these amendments are effective prospectively for reporting periods beginning after December 15, 2012. Other than a change in presentation, the adoption of this guidance did not have a material impact on the Company’s consolidated financial statements.

	In July 2013, the FASB issued guidance to address the diversity in practice related to the financial statement presentation of unrecognized tax benefits as either a reduction of a deferred tax asset or a liability when a net operating loss carryforward, a similar tax loss or a tax credit carryforward exists. This guidance is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.
