Trident files for Chapter 11 bankruptcy protection

SAN DIEGO (AP) -- Entropic Communications will spend $55 million acquiring assets from Trident Microsystems Inc., which is under Chapter 11 bankruptcy protection.

Trident has asked the Delaware bankruptcy court to approve the sale of its set-top-box operations to Entropic, a chip maker, the company said Wednesday. Trident said it plans to continue to operate its businesses while it goes through the bankruptcy approval process regarding this sale and will look for "strategic alternatives" for its other business units.

Entropic makes chips for home entertainment networks. It said the acquisition would "bring together two highly complementary technologies, product lines, and teams" and expand the market it serves.

Shares of Entropic Communications Inc. climbed 8 cents to $5.58 in premarket trading.
