Release Details

AUSTIN, Texas, May 23, 2006 (BUSINESS WIRE) -- Silicon Laboratories Inc. (Nasdaq:SLAB) today announced that Samsung Electronics has adopted the Si4700 FM tuner across several handset and MP3 platforms. Fully integrated and tested, Silicon Laboratories' Si4700 allowed Samsung to quickly implement FM radio functionality into multiple new handsets resulting in superior FM radio performance, unmatched FM system integration and industry-leading reliability and manufacturability.

Silicon Laboratories' FM tuner leverages a patented digital architecture and 100 percent CMOS process technology to deliver the entire solution from antenna input to audio output while significantly improving performance. This completely integrated solution requires only one external supply bypass capacitor and less than 20 mm2 of board space. The Si4700 integrates selectivity filtering, automatic gain control, a frequency synthesizer and audio processing.

"Samsung's quick adoption of the highly differentiated Si4700 is a testament to the ease-of-use and unmatched performance achievable with our FM radio tuner," said Tyson Tuttle, vice president of Silicon Laboratories. "Our proven digital architecture has resulted in an elegant, high-performance solution, enabling customers like Samsung to easily and cost-effectively implement world-class FM stereo as a standard feature on any cellular handset or portable audio device."

Leveraging Silicon Laboratories' proven Aero® digital low-IF receiver architecture, frequency synthesizer technology and patented MCU embedded processing technology, the Si4700 delivers superior RF performance and interference rejection. The innovative digital architecture enables the highest level of selectivity and sensitivity performance resulting in improved reception and superior audio quality under varying reception conditions compared to conventional portable radio tuners.

In addition, Silicon Laboratories is a certified Samsung Electronics Eco-Partner Affiliate Company recognized for its control of substances with environmental impacts as well as its stable environmental quality control systems.
