POWER OF ATTORNEY
Know all by these present, that TOM SUN ("Principal") hereby constitutes and
appoints each of Alinka Flaminia, Steven J. Geiser and Amr Razzak or any of them
signing singly, and with full power of substitution, Principal's true and lawful
attorney-in-fact to:
(1) prepare, execute in Principal's name and on Principal's behalf, and submit
to the U.S. Securities and Exchange Commission (the "SEC") a Form ID (or any
successor form), including amendments thereto, and any other documents necessary
or appropriate to obtain codes and passwords enabling Principal to make
electronic filings with the SEC of reports required by Section 16(a) or any rule
or regulation of the SEC promulgated thereunder;
(2) execute for and on behalf of the undersigned, in Principal's capacity as
Director of PMC-Sierra, Inc. (the "Company"), Forms 3, 4, and 5 (or any
successor form or forms) in accordance with Section 16(a) of the Securities
Exchange Act of 1934 and the rules thereunder;
(3) do and perform any and all acts for and on behalf of Principal which may
be necessary or desirable to complete and execute any such Forms, complete and
execute any amendment or amendments thereto, and file such form with the SEC and
any stock exchange or similar authority; and
(4) take any other action of any type whatsoever in connection with the
foregoing which, in the opinion of such attorney-in-fact, may be of benefit to,
in the best interest of, or legally required by, Principal, it being understood
that the documents executed by such attorney-in-fact on behalf of Principal
pursuant to this Power of Attorney shall be in such form and shall contain such
terms and conditions as such attorney-in-fact may approve in such
attorney-in-fact's discretion.
Principal hereby grants to each such attorney-in-fact full power and authority
to do and perform any and every act and thing whatsoever requisite, necessary,
or proper to be done in the exercise of any of the rights and powers herein
granted, as fully to all intents and purposes as Principal might or could do if
personally present, with full power of substitution or revocation, hereby
ratifying and confirming all that such attorney-in-fact's substitute or
substitutes, shall lawfully do or cause to be done by virtue of this power of
attorney and the rights and powers herein granted. Principal acknowledges that
each such attorney-in-fact, in serving in such capacity at the request of
Principal, is not assuming, nor is the Company assuming any of Principal's
responsibilities to comply with Section 16 of the Securities Exchange Act of
1934.
This Power of Attorney shall remain in full force and effect until Principal is
no longer required to file Forms 3, 4, and 5 (or successor forms) with respect
to Principal's holdings of and transactions in securities issued by the Company,
unless earlier revoked by Principal in a signed writing delivered to any of the
foregoing attorneys-in-fact. This Power of Attorney does not revoke or replace
any other power of attorney that Principal has previously granted.
IN WITNESS WHEREOF, the undersigned have caused this Power of Attorney to be
executed as of the dates specified below.
