Sony Ericsson Adopts Silicon Laboratories' FM Radio Tuner for the W950 Walkman(R) Phone; Si4701 Offers Superior Performance and IntegrationAUSTIN, Texas--(BUSINESS WIRE)--Aug. 7, 2006--Silicon Laboratories Inc. (Nasdaq:SLAB) today announced that Sony Ericsson has adopted the Si4701 FM tuner for the W950 Walkman® phone. By using the highly-integrated Silicon Laboratories Si4701 with support for the Radio Data System (RDS), Sony Ericsson quickly implemented outstanding FM stereo receiver functionality in less than 20 mm2 of board area on the ultra-slim, stylish, UMTS-enabled W950 Walkman® phone with mobile music capability.

The Silicon Laboratories Si4701 incorporates a digital processor for the RDS and the Radio Broadcast Data System (RBDS), which includes all the required RDS/RBDS symbol decoding, block synchronization and error detection and correction functions. This feature enables Sony Ericsson to provide FM broadcast data such as song title, artist, and station name on the W950 Walkman® phone. The Si4701 is pin compatible to the non-RDS part, the Si4700.

"Consumers are demanding handsets with music functionality for both feature-rich phones and entry-level handsets," said Tyson Tuttle, vice president of Silicon Laboratories. "The performance, integration and ease-of-use of our FM tuner products allow manufacturers like Sony Ericsson to quickly implement world-class FM stereo as a standard feature on any handset or portable media device."

The Si4701 reduces cost while enabling superior sound quality and adjustability in critical FM receiver specifications. Using patented technology including a field-proven, low IF digital architecture and embedded processor technology, Silicon Laboratories' FM tuners offer industry-leading performance in all FM receiver specifications and excel in real-world environments such as large cities where high immunity to blockers is critical for good reception. The devices provide software programmability for the seek, soft mute and stereo blend parameters, all of which are fundamental to superior performance in highly variable FM broadcast environments.
