Exhibit 10.1

PMC-SIERRA, INC.

RESTRICTED STOCK UNIT AGREEMENT

(Performance-Based Vesting Award)

RECITALS

A. The Board has adopted the Plan for the purpose of attracting and retaining the best available personnel for positions of substantial responsibility, to provide additional incentive to eligible employees, consultants and directors and to promote the success of the Company’s business.

B. Participant is to render valuable services to the Company (or a Parent or Subsidiary), and this Agreement is executed pursuant to, and is intended to carry out the purposes of, the Plan in connection with the Company’s issuance of shares of Common Stock to Participant under the Plan.

C. The Plan permits the granting of awards in a manner which is intended to constitute compensation deductible by the Company for tax purposes under Section 162(m) of the Code.

D. All capitalized terms in this Agreement shall have the meaning assigned to them herein or in the attached Appendix A.

NOW, THEREFORE, it is hereby agreed as follows:

1. Grant of Performance-Based Vesting Restricted Stock Units. The Company hereby grants to Participant, as of the Award Date, performance-based vesting restricted stock units under the Plan (the “Award”). Each performance-based restricted stock unit (“RSU”) represents the potential right to receive one share of Common Stock (each a “Share”) on the specified issuance date following the vesting of that RSU, subject to the achievement of the performance goal or goals during the performance period described in this Agreement. The number of shares of Common Stock subject to the Award, the performance goal or goals applicable to those shares, the applicable vesting schedule for those shares, the date on which those vested shares shall become issuable to Participant and the remaining terms and conditions governing the Award shall be as set forth in this Agreement.

2. Cessation of Employment or Service. Should Participant’s Continuous Status as an Employee, Consultant or Director cease for any reason prior to vesting in one or more Shares subject to this Award, then the Award shall be immediately cancelled with respect to those unvested Shares. Participant shall thereupon cease to have any right or entitlement to receive any Shares under those cancelled RSUs. Notwithstanding the foregoing, in the event Participant’s employment terminates in a manner that entitles him to the equity acceleration benefits (the “Acceleration Benefits”) described in Section 8 or 9 of that certain Amended and Restated Executive Employment Agreement by and between the Company and Participant effective as of February 22, 2012 (the “Employment Agreement”), solely for purposes of determining the number of the Shares underlying the RSUs that will vest upon such termination of employment pursuant to the Acceleration Benefits, (i) to the extent the number of Earned RSUs has not been determined by the Compensation Committee as of the date Participant’s employment terminates, the number of Earned RSUs subject to vesting shall be the Target Number of RSUs and (ii) the Acceleration Benefits shall be calculated as of the date of Participant’s Separation from Service (as defined in the Employment Agreement), including in such case as the Performance Period has not concluded as of such date.

3. Limited Transferability. Prior to the actual issuance of the Shares that vest hereunder, Participant may not transfer any interest in the Award or the underlying Shares; provided, however, any Shares which vest hereunder but which otherwise remain unissued at the time of Participant’s death may be transferred (subject to applicable law) pursuant to the provisions of Participant’s will or the laws of descent or distribution.

4. Stockholder Rights. The holder of this Award shall not have any stockholder rights, including voting or dividend rights, with respect to the Shares subject to the Award until Participant becomes the record holder of those Shares following their actual issuance upon the Company’s collection of the applicable Withholding Taxes.

5. Adjustment in Shares. In the event of any increase or decrease in the number of issued shares of Common Stock resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Common Stock, or any other increase or decrease in the number of issued shares of Common Stock effected without receipt of consideration by the Company (other than a conversion of any convertible securities of the Company) then the number of Shares subject to this Award shall be adjusted proportionately by the Board.

6. Collection of Withholding Taxes.

(a) Until such time as the Company provides Participant with written or electronic notice to the contrary, the Company shall collect the Withholding Taxes required to be withheld with respect to the issuance of the vested Shares hereunder through an automatic share withholding procedure pursuant to which the Company shall withhold, at the time of such issuance, a portion of the Shares with a Fair Market Value (measured as of the issuance date) equal to the amount of those taxes (the “Share Withholding Method”); provided, however, that the amount of any Shares so withheld shall not exceed the minimum statutory amount required to be withheld by the Company. Notwithstanding the foregoing, the Administrator may, at its sole discretion, require that such Withholding Taxes be paid through one of the following methods selected by the Administrator in lieu of the Share Withholding Method:

(i) Participant’s delivery of his or her separate check payable to the Company in the amount of such taxes, or

(ii) the use of the proceeds from a next-day sale of the Shares issued to Participant, provided and only if (A) such a sale is permissible under the Company’s trading policies governing the sale of Common Stock, (B) Participant makes an irrevocable commitment, on or before the issuance date for those Shares, to effect such sale of the Shares and (C) the transaction is not otherwise deemed to constitute a prohibited loan under Section 402 of the Sarbanes-Oxley Act of 2002.

(b) Notwithstanding the provisions of subparagraph (a) of this Paragraph 6, the employee portion of any U.S. federal, state and local employment taxes and any foreign taxes or payments required to be withheld by the Company in connection with the

4

vesting of the Shares (the “Employment Taxes”) shall in all events be collected from Participant no later than the last business day of the calendar year in which the Shares vest hereunder. Accordingly, to the extent the issuance date for one or more vested Shares is to occur in a year subsequent to the calendar year in which those Shares vest, Participant shall, on or before the last business day of the calendar year in which the Shares vest (or at such time as determined by the Company), deliver to the Company a check payable to its order in the dollar amount equal to the Employment Taxes required to be withheld with respect to those Shares.

7. Compliance with Laws and Regulations. The issuance of shares of Common Stock pursuant to the Award shall be subject to compliance by the Company and Participant with all applicable requirements of law relating thereto and with all applicable regulations of any stock exchange on which the Common Stock may be listed for trading at the time of such issuance.

8. Notices. Any notice required to be given or delivered to the Company under the terms of this Agreement shall be in writing and addressed to the Company at its principal corporate offices. Except to the extent electronic notice is expressly authorized hereunder, any notice required to be given or delivered to Participant shall be in writing and addressed to Participant at the most recent residential address on file at the Company (its Parent or Subsidiary). All notices shall be deemed effective upon personal delivery (or electronic delivery to the extent authorized hereunder) or upon deposit in the U.S. mail, postage prepaid and properly addressed to the party to be notified.

9. Successors and Assigns. Except to the extent otherwise provided in this Agreement, the provisions of this Agreement shall inure to the benefit of, and be binding upon, the Company and its successors and assigns and Participant, Participant’s assigns and the legal representatives, heirs and legatees of Participant’s estate.

10. Construction. This Agreement and the Award evidenced hereby are made and granted pursuant to the Plan and are in all respects limited by and subject to the terms of the Plan. All decisions of the Administrator with respect to any question or issue arising under the Plan or this Agreement shall be conclusive and binding on all persons having an interest in the Award.

11. Governing Law. The interpretation, performance and enforcement of this Agreement shall be governed by the laws of the State of Delaware without resort to that State’s conflict-of-laws rules.

12. Employment at Will. Nothing in this Agreement or in the Plan shall confer upon Participant any right to continue in employment or service for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Company (or any Parent or Subsidiary employing or retaining Participant) or of Participant, which rights are hereby expressly reserved by each, to terminate Participant’s Continuous Status as an Employee, Consultant or Director at any time for any reason, with or without cause, subject to applicable law and the terms of any employment agreement.

13. Nature of Grant; No Entitlement; No Claim for Compensation. In accepting the grant of this Award for the number of Shares as specified above, Participant acknowledges the following:

(a) The Plan and any sub-plans and addenda thereto are established voluntarily by the Company, they are discretionary in nature and may be modified, amended, suspended or terminated by the Company at any time.

(b) The grant of this Award is voluntary and occasional and does not create any contractual or other right to receive future grants of awards, or benefits in lieu of awards, even if awards have been granted repeatedly in the past.

(c) All decisions with respect to future awards, if any, will be at the sole discretion of the Administrator.

(d) Participant is voluntarily participating in the Plan.

(e) This Award is an extraordinary item that does not constitute compensation of any kind for services of any kind rendered to the Company or its Parent or Subsidiaries (including, as applicable, Participant’s employer) and which is outside the scope of Participant’s employment contract, if any.

(f) This Award is not part of normal or expected compensation or salary for any purpose, including, but not limited to, calculating any severance, resignation, termination, redundancy, end of service payments, bonuses, long-service awards, pension or retirement benefits or similar payments.

(g) In the event that Participant’s employer is not the Company, the grant of the Award shall not be interpreted to form an employment contract or relationship with the Company and, furthermore, the grant of the Award shall not be interpreted to form an employment contract with Participant’s employer or any Parent or Subsidiary.

(h) The future value of the Shares underlying the Award is unknown and cannot be predicted with certainty.

(i) In consideration of the grant of this Award, no claim or entitlement to compensation or damages shall arise from termination of the Award or diminution in value of the Award or any of the Shares issuable under the Award from termination of Participant’s employment by the Company or Participant’s employer, as applicable (and for any reason whatsoever and whether or not in breach of contract or local labor laws), and Participant irrevocably releases his or her employer, the Company and its Subsidiaries, as applicable, from any such claim that may arise; if, notwithstanding the foregoing, any such claim is found by a court of competent jurisdiction to have arisen, then, by accepting this Agreement, Participant shall be deemed to have irrevocably waived his or her entitlement to pursue such claim.

14. Data Privacy.

(a) Participant hereby explicitly and unambiguously consents to the collection, use and transfer, in electronic or other form, of Participant’s personal data as described in this Agreement by and among, as applicable, Participant’s employer, the Company and its Parent and Subsidiaries for the exclusive purpose of implementing, administering and managing Participant’s participation in the Plan.

Participant understands that the Data may be transferred to any third parties assisting in the implementation, administration and management of the Plan, that these recipients may be located in Participant’s country, or elsewhere, and that the recipient’s country may have different data privacy laws and protections than Participant’s country. Participant understands that Participant may request a list with the names and addresses of any potential recipients of the Data by contacting stockholder services at the Company.
