Microtune COO Steps Down


Just days after winning a major court decision over mortal enemy Broadcom
Corp., Microtune Inc. president and chief operating officer William H. Housley
resigned abruptly Friday.

Chairman and CEO Douglas Bartek will assume Housley's duties, but there are
no immediate plans to seek another COO, according to a terse company

The Plano, Texas-based maker of silicon and radio-frequency tuners used in
cable modems and transmission gear scored a victory recently in its protracted
legal battle with Broadcom when a Texas jury found that Broadcom had willfully
violated a Broadcom cable-modem-tuner patent.

A U.S. District Court judge has followed up that ruling, issuing a temporary
restraining order barring Broadcom for making or selling the tuner in

But the company is also facing questions about its accounting practices. In
February, it launched an investigation into a series of fourth-quarter-2002
charges that sapped much of its revenue. Microtune has ordered its audit
committee to look into the matter and has notified the Securities and Exchange
Commission of the investigation.

And it faces continued legal wrangling with Broadcom. The chip-making giant
has filed a countersuit against Microtune charging violations of its
electrostatic-discharge-protection circuits and wireless-technology patents, and
in March, it filed a complaint with the U.S. International Trade Commission
charging Microtune with importing tuners and other components that infringe on
its intellectual property.
