Item 7.01      Regulation FD Disclosure.

On June 25, 2014, June 26, 2014 and July 3, 2014, respectively, three complaints were filed in the Superior Court of California, County of Santa Clara, against PLX Technology, Inc. (“PLX”), its directors and certain officers, and Avago Technologies Limited (“Avago”), Avago Technologies Wireless (U.S.A.) Manufacturing Inc., a Delaware corporation and wholly owned subsidiary of Avago (“Avago Wireless”), and Pluto Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Avago Wireless (“Pluto” and collectively with Avago and Avago Wireless, the “Avago Entities”).  Additionally, on June 27, 2014, two complaints were filed, and on July 2, 2014, a third complaint was filed, in the Court of Chancery of the State of Delaware against PLX, its directors and certain officers, and the Avago Entities. The six cases are putative class actions brought by purported stockholders alleging, among other things, that the PLX Board of Directors breached their fiduciary duties by approving the Agreement and Plan of Merger, dated as of June 23, 2014, between Avago Wireless, Pluto and PLX, and that PLX and the Avago Entities aided and abetted these alleged breaches of fiduciary duty. All six complaints seek, among other things, either to enjoin the proposed transaction or to rescind it should it be consummated, as well as money damages.

Copies of the complaints are furnished as exhibits 99.1, 99.2, 99.3, 99.4, 99.5 and 99.6 to this Current Report on Form 8-K and the contents therein are incorporated by reference in this Item 7.01.
