Exhibit 3.1  RESTATED CERTIFICATE OF INCORPORATION  OF  VITESSE SEMICONDUCTOR CORPORATION  The
undersigned does hereby certify as follows on behalf of Vitesse Semiconductor
Corporation (the Corporation), a corporation organized and existing
under the General Corporation Law of Delaware, for the purpose of integrating
and restating its Certificate of Incorporation:  ONE:  The present name of the Corporation is
Vitesse Semiconductor Corporation.  TWO:  The Corporation filed its Certificate of
Incorporation under the name Vitesse Semiconductor Corporation with the
Secretary of State of Delaware on January 10, 1992, which it subsequently
amended on February 10, 1997, February 12, 1998, September 16,
1999, March 6, 2000, January 7, 2010, June 30, 2010 and August 5,
2010.  THREE:  The following Restated Certificate of
Incorporation was duly adopted by the Corporations Board of Directors in
accordance with the provisions of Section 245 of the General Corporation
Law of Delaware and only restates and integrates and does not further amend the
provisions of the Corporations Certificate of Incorporation as heretofore
amended and supplemented, and there is no discrepancy between those provisions
and the following:  1.   The
name of the corporation is Vitesse Semiconductor Corporation (the Corporation).  2.   The
address of the Corporations registered office in the State of Delaware is
Corporation Trust Center, 1209 Orange Street, in the City of Wilmington, County
of New Castle, zip code 19801.  The name
of its registered agent at such address is The Corporation Trust Company.  3.   The
nature of the business or purposes to be conducted or promoted by the
Corporation is to engage in any lawful act or activity for which Corporations
may be organized under the General Corporation Law of Delaware.  4.   This
Corporation is authorized to issue two classes of shares to be designated
respectively Preferred Stock (Preferred) and Common Stock (Common).
The total number of shares of Preferred this Corporation shall have authority
to issue shall be 10,000,000, $0.01 par value, and the total number of Common
this Corporation shall have authority to issue shall be 250,000,000, $0.01 par
value.  The
Preferred may be issued from time to time in one or more series pursuant to a
resolution or resolutions providing for such issue duly adopted by the Board of
Directors (authority to do so being hereby expressly vested in the Board). The
Board of Directors is further authorized to determine or alter the rights,
preferences, privileges and restrictions  1


granted
to or imposed upon any wholly unissued series of Preferred and, to fix the
number of shares of any series of Preferred and the designation of any such
series of Preferred. The Board of Directors, within the limits and restrictions
stated in any resolution or resolutions of the Board of Directors originally
fixing the number of shares constituting any series, may increase or decrease
(but not below the number of shares in any such series then outstanding) the
number of shares of any series subsequent to the issue of shares of that
series.  4.1Designation and Rights and
Preferences of Series B Participating Non-Cumulative Convertible Preferred
Stock.  4.1.1Designation.  The distinctive serial designation of this
series shall be Series B Participating Non-Cumulative Convertible
Preferred Stock (hereinafter called Series B).  All capitalized terms used herein and not
otherwise defined shall have the meanings set forth in Section 4.1.7
hereof.  Each share of Series B
shall be identical in all respects with the other shares of Series B.  The Series B shall consist of 800,000
shares with a par value of $0.01 per share. 
Shares of Series B purchased by the Corporation, canceled pursuant
to Section 4.1.3 below or converted into the common stock, par value $0.01
per share of the Corporation (Common Stock), shall be canceled and
retired and shall revert to authorized but unissued preferred stock of the
Corporation undesignated as to series.  4.1.2.Dividends.  The holders of shares of Series B shall
be entitled to receive, when, as and if declared by the Board of Directors, but
after and subject to the payment in full of all amounts required to be
distributed to the holders of Senior Stock and then only out of funds legally
available therefor, dividends and distributions (payable in cash, stock or
otherwise, other than any stock dividend for which there is an adjustment
pursuant to Section 4.1.5 below), on each date that dividends or other
distributions are payable on or in respect of any Common Stock in an amount
equal to ten percent (10%) of par value per share plus the amount of dividends
that would have been payable with respect to the shares of common stock
issuable upon conversion of such shares of Series B had such shares of Series B
fully converted (excluding for such purpose, the restrictions of Section 4.1.5(l))
immediately prior to the record date for such dividends.  All dividends or distributions payable with
respect to the shares of Series B pursuant to this Section 4.1.2
shall be payable in respect of fractional shares, adjusted to reflect such
fractional dividend or distribution. 
Such dividends or distributions shall be non-cumulative and shall be
payable on the date specified by the Board of Directors of the Corporation at
the time such dividend is declared.  4.1.3.Liquidation Preference.  In the event of any Liquidation, after and
subject to the payment in full of all amounts required to be distributed to the
holders of Senior Stock, the Series B shall be canceled and the holders of
shares of Series B shall thereafter be entitled to be paid out of the
assets of the Corporation or proceeds thereof available for distribution on a
pro-rata basis amongst the holders of the Common Stock and the holders of the Series B
in an amount equal to the amount such holders would receive if such shares of Series B
had been converted into Common Stock immediately prior to the distribution of
such remaining assets.  2


4.1.4.Redemption.  The Series B may not be redeemed by the
Corporation at any time.  4.1.5.Conversion.  (a)Subject to the provisions
for adjustment hereinafter set forth, each share of Series B shall be
convertible at the option of the holder thereof, at any time, into five (5) fully
paid and nonassessable shares of Common Stock (and any fractional share of Series B
Preferred Stock shall be convertible on the same proportional basis), upon
surrender at the principal office of the Corporation or at such other office or
offices as the Board of Directors may designate of the certificate for the
share so to be converted, duly endorsed or assigned to the Corporation in blank
and accompanied by (i) an irrevocably written notice to the Corporation
that the holder thereof elects so to convert such share of Series B and
specifying the name or names (with address or addresses) in which a certificate
or certificates evidencing share(s) of Common Stock are to be issued and (ii) if
required pursuant to Section 4.1.5(f), an amount sufficient to pay any
transfer or similar tax (or evidence reasonably satisfactory to the Corporation
demonstrating that such taxes have been paid). 
If a holder converts more than one share of Series B at a time, the
number of full shares of Common Stock issuable upon conversion shall be based
on the total number of shares of Series B so converted.  Subject to the following provisions of this
paragraph, each conversion shall be deemed to have been effected immediately prior
to the close of business on the date on which the certificates for shares of Series B
to be converted shall have been surrendered together with the irrevocable
written notice and payment of taxes (if applicable) as provided for above, and
the person or persons entitled to receive the Common Stock deliverable upon
conversion of such shares of Series B shall be treated for all purposes as
the record holder or holders of such Common Stock at such time on such date,
unless the stock transfer books of the Corporation shall be closed on such
date, in which event such person or persons shall be deemed to have become such
holder or holders of record at the close of business on the next succeeding day
on which such stock transfer books are open, but such conversion shall be at
the conversion rate in effect on the date on which such shares of Series B
shall have been surrendered and such notice (and, if applicable, payment)
received by the Corporation.  (b)The number of shares of
Common Stock and the number of any other shares of the Corporation, if any,
into which each share of Series B is convertible, shall be adjusted from
time to time as set forth below.  Such
adjustments shall be made whether or not there are any outstanding shares of Series B,
and any shares of Series B subsequently issued shall be issued with such
adjustments having been effected.  (i)Dividends,
Subdivisions, Splits and Combinations.  In case the Corporation shall (A) pay a
dividend or make a distribution in shares of Common Stock or shares convertible
into or otherwise exchangeable or exercisable for Common Stock, (B) subdivide
or split its outstanding shares of Common Stock into a greater number of shares
of Common Stock or (C) combine or reverse-split its outstanding shares of
Common Stock into a smaller number of shares of Common Stock, then in each such
case the number of shares of Common Stock into which each share of Series B
shall thereafter be convertible shall be  3


proportionately
increased or decreased, respectively, with effect as of the record date set for
such dividend or the effective date of such split, subdivision or combination.  (ii)Reclassifications.  In the case of any classifications,
reclassifications or reorganizations of the Common Stock (whether pursuant to a
sale of all or substantially all assets, merger or consolidation or otherwise)
for which an adjustment is not otherwise made pursuant to this Section 4.1.5
and for which no cancellation is effected under Section 4.1.3, then the
holder of each share of Series B shall be entitled to receive upon the
conversion of such share (on the same basis and conditions as set forth herein
with respect to the Common Stock), the stock, securities or other property
(including cash) that such holder would have been entitled to receive upon the
happening of any of the events described above had such share been converted
immediately prior to the happening of such event and, in any such case,
appropriate provision shall be made so that such holders rights and interests
herein with respect to the Series B (including in this Section 4.1.5)
shall be applicable as nearly as may be practicable in relation to stock,
securities or other property thereafter deliverable upon conversion.  (c)In case the Corporation
shall take a record of the holders of any class of its capital stock entitled
to receive a dividend or other distribution payable in Common Stock or
securities convertible into or otherwise exchangeable or exercisable for Common
Stock, whether or not immediately exercisable (collectively, Convertible
Securities) or to subscribe for or purchase or otherwise acquire Common
Stock or Convertible Securities, then such record date shall be deemed to be
the date of issue or sale of the shares deemed to have been issued or sold upon
the declaration of such dividend or other distribution or the granting of such
right of subscription, purchase or acquisition.  (d)Whenever any adjustment is
required in the shares of Common Stock into which each share of Series B
is convertible, the Corporation shall forthwith (i) file in the corporate
minutes and with any transfer agent of the Series B a statement describing
in reasonable detail the adjustment and the method of calculation used and (ii) cause
a copy of such statement to be mailed to the holders of record of shares of Series B
as of the effective date of such adjustment.  (e)The Corporation shall at all
times reserve and keep available out of its authorized but unissued Common
Stock, for the purpose of issuance upon conversion of the Series B, the
full number of shares of Common Stock then deliverable upon the conversion of
all shares of Series B then outstanding.  (f)The Corporation will pay any
and all taxes that may be payable in respect of the issuance or delivery of
Common Stock on conversion of Series B. 
The Corporation shall not, however, be required to pay any tax which may
be payable in respect of any transfer involved in the issuance and delivery of
Common Stock in a name other than that in which the Series B so converted
were registered, and no such issuance  4


or
delivery shall be made unless and until (i) the person requesting such
issuance has paid to the Corporation the amount of any such tax or has
established to the satisfaction of the Corporation that such tax has been paid
and (ii) such issuance and delivery is permitted under applicable federal,
state and foreign securities laws without registration thereof.  (g)For the purpose of this Section 4.1.5
and, unless the context otherwise requires, the purpose of this serial
designation, the term Common Stock shall include any shares of the
Corporation of any class or series which has no preference or priority in the
payment of dividends or in the distribution of assets upon any Liquidation of
the Corporation and which is not subject to redemption by the Corporation.  However, Common Stock issuable upon
conversion of Series B shares shall include only shares of the class
designated as Common Stock as of the original date of issuance of the Series B,
or shares of the Corporation of any classes or series resulting from any
reclassification or reclassifications thereof and which have no preference or
priority in the payment of dividends or in the distribution of assets upon any
Liquidation of the Corporation and which are not subject to redemption by the
Corporation, provided that if at any time there shall be more than one such
resulting class or series, the shares of such class and series then so issuable
shall be substantially in the proportion which the total number of shares of
such class and series resulting from all such reclassifications bears to the
total number of shares of all such classes and series resulting from all such
reclassifications.  (h)No fractional shares of
Common Stock shall be issued upon the conversion of any share or shares of Series B.  If any such conversion would otherwise
require the issuance of a fractional share, an amount equal to the fair market
value of such fractional share, as determined in good faith by the Board of
Directors, shall be paid to the holder in cash by the Corporation.  (i)The certificate of any
independent firm of public accountants or any independent investment bank or
financial advisory firm of nationally recognized standing selected in good
faith by the Board of Directors shall be presumptive evidence of the
correctness of any computation made under this Section 4.1.5.  (j)Notwithstanding any other
provision hereof, if a conversion of this security is to be made in connection
with a holders participation in a registered public offering or a Sale
Transaction, the conversion may, at the election of the holder, be conditioned
upon the consummation of such public offering or Sale Transaction in which case
such conversion shall not be deemed to be effective until the consummation of
such transaction.  (k)In case at any time or from
time to time the Corporation shall take any action of the type contemplated
herein but not expressly provided for by such provisions, then, unless in the
opinion of the Board of Directors such action is not reasonably likely to have
a material adverse effect upon the rights of the Series B (taking into
consideration, if necessary, any prior actions which the Board of Directors
hereunder deemed not reasonably likely to materially adversely affect the
rights of the Series B), the Series B shall be adjusted  in such manner and at such time as the Board
of Directors may in good faith determine to be equitable in the circumstances.  5


(l)Notwithstanding any other
provision hereof, a holder of shares of Series B will only be entitled to
the conversion referred to in this Section 4.1.5 to the extent (and only
to the extent) that the receipt of Common Stock upon such conversion would not
cause the holder (including its affiliated persons within the meaning of Section 3(a)(19)
of the Securities Exchange Act of 1934, as amended (the Exchange Act),
and the rules and regulations promulgated thereunder) to become, directly
or indirectly, a beneficial owner (within the meaning of Section 13(d) of
the Exchange Act and the rules and regulations promulgated thereunder) of
more than 9.99% of the shares of the Common Stock outstanding at such
time.  Any purported delivery of shares
of Common Stock upon conversion of the Series B shall be void and have no
effect to the extent (but only to the extent) that such delivery would result
in the Series B holder (including its affiliated persons) becoming the
beneficial owner of more than 9.99% of the shares of Common Stock outstanding
at such time.  Notwithstanding anything
to the contrary herein, the Series B holder shall not be entitled, with or
without the consent of the Corporation, to waive the restrictions set forth in
this Section 4.1.5(l).  At any time
while this Section 4.1.5(l) would operate as a restriction on the
conversion of the Series B, the Corporation shall deliver, upon request by
any Series B holder, a certified statement by the Chief Financial Officer
to such Series B holder of the number of shares of the Corporations
Common Stock outstanding as of a particular date, and the Series B holder
shall be entitled to rely on such certified statement in making its
determination as to whether the conversion of the Series B would be
permissible under this Section 4.1.5(l). Notwithstanding anything to the
contrary contained herein, the Corporation shall have no obligation to verify
whether the Series B holder would be deemed to be the beneficial owner of
any shares of Common Stock or to verify whether the Series B holder has
correctly calculated whether the conversion of the Series B is permissible
under this Section 4.1.5(l).  4.1.6.Voting Rights.  Except as may be required by law, the holders
of Series B shall not have voting rights.  4.1.7.Definitions.  As
used herein with respect to Series B, the following terms shall have the
following meanings:  (a)Liquidation shall
mean any voluntary or involuntary liquidation, dissolution or winding up of the
affairs of the Corporation or the consummation of any Sale Transaction.  (b)Sale Transaction
shall mean the voluntary sale, conveyance, exchange or transfer (for cash,
shares of stock, securities or other consideration) of all or substantially all
the property or assets of the Corporation to, or the consolidation or merger of
the Corporation with or into, one or more other corporations or other entities,
where the stockholders of the Corporation immediately prior to such transaction
do not thereafter beneficially own, collectively, at least a majority of the
shares of capital stock entitled to vote generally in election of directors or
persons performing a similar function of the surviving or successor corporation
or other entity.  The good faith
determination of a  6


majority
of the Board of Directors (or persons performing a similar function of a
successor entity) that a Sale Transaction has occurred shall conclusively
establish the occurrence of such event.  (c)Senior Stock shall
mean any class or series of stock or other security of the Corporation
hereafter authorized in accordance with the certificate of incorporation of the
Corporation by the terms of which the holders of shares of such shares of such
class or series would be entitled to the receipt of dividends and of amounts
distributable upon Liquidation or redemption in preference or priority to the
holders of shares of Series B.  4.1.8.Replacement Certificates.  The Corporation shall replace any mutilated
certificates representing shares of Series B at the holders expense upon
surrender of such certificates to the Corporation.  The Corporation shall replace any
certificates representing shares of Series B that become destroyed, stolen
or lost at the holders expense upon delivery to the Corporation of reasonably
satisfactory evidence that such certificates have been destroyed, stolen or
lost.  4.1.9.Miscellaneous.  The shares of Series B shall not have
any relative, participating, optional, conversion, voting or other special
rights and powers other than as set forth herein.  In the event that the Corporation shall at
any time be party to a transaction or series of transactions that constitute a
sale of all or substantially all assets, a holding company reorganization or
any other merger or consolidation pursuant to which in each case all of the
Common Stock shall be exchanged for equity securities in another entity, the
Corporation agrees that the entity resulting from, or issuing securities in,
such transaction or series of transactions shall be deemed the successor to the
Corporation pursuant to this instrument and shall assume all of the Corporations
rights and obligations hereunder.  4.1.10.Severability of Provisions.  If any powers, preferences or relative,
participating, optional or other rights of the Series B or qualifications,
limitations or restrictions thereof set forth in this designation (as it may be
amended from time to time) are invalid, unlawful or incapable of being enforced
by reason of any rule or law or public policy, all other powers,
preferences and relative, participating, optional and other rights of Series B
and qualifications, limitations and restrictions being given effect thereby set
forth in this designation (as so amended), which can be given effect without
the invalid, unlawful or unenforceable powers, preferences and relative,
participating, optional and other rights to Series B and qualifications,
limitations and restrictions thereof, shall, nevertheless, remain in full force
and effect, and no powers, preferences or relative, participating, optional or
other rights of Series B or qualifications, limitations and restrictions
thereof herein set forth shall be deemed dependent upon any other such powers,
preferences or relative, participating, optional or other rights of Series B
or qualifications, limitations and restrictions thereof unless so expressed
herein.  5.   The
Corporation is to have perpetual existence.  7


6.   Elections
of directors need not be by written ballot unless a stockholder demands
election by written ballot at the meeting and before voting begins or unless
the Bylaws of the Corporation shall so provide.  7.   The
number of directors which constitute the whole Board of Directors of the
Corporation shall be designated in the Bylaws of the Corporation.  8.   In
furtherance and not in limitation of the powers conferred by statute, the Board
of Directors is expressly authorized to make, alter, amend or repeal the Bylaws
of the Corporation.  9.   (a) 
To the fullest extent permitted by the Delaware General Corporation Law as the
same exists or as may hereafter be amended, a director of the Corporation shall
not be personally liable to the Corporation or its stockholders for monetary
damages for breach of fiduciary duty as a director.  (b) 
The Corporation shall indemnify to the fullest extent permitted by law any
person made or threatened to be made a party to an action or proceeding, whether
criminal, civil, administrative or investigative, by reason of the fact that
he, his testator or intestate is or was a director, officer or employee of the
Corporation or any predecessor of the Corporation or serves or served at any
other enterprise as a director, officer or employee at the request of the
Corporation or any predecessor to the Corporation.  (c) 
Neither any amendment nor repeal of this Article 9, nor the adoption of
any provision of this Corporations Certificate of Incorporation inconsistent
with this Article 9, shall eliminate or reduce the effect of this Article 9
in respect of any matter occurring, or any action or proceeding accruing or
arising or that, but for this Article 9, would accrue or arise, prior to
such amendment, repeal or adoption of an inconsistent provision.  10.  Meetings of stockholders may be held within
or without the State of Delaware, as the Bylaws may provide.  The books of the Corporation may be kept
(subject to any provision contained in the statutes) outside of the State of
Delaware at such place or places as may be designated from time to time by the
Board of Directors or in the Bylaws of the Corporation.  11.  Following the effectiveness of the
registration of any class of securities of the Corporation pursuant to the
requirements of the Securities Exchange Act of 1934, as amended, no action
shall be taken by the stockholders of the Corporation except at an annual or
special meeting of the stockholders call in accordance with the Bylaws and no
action shall be taken by the stockholders by written consent.  8
