Silicon Labs announces the Si470x FM tuner family, integrated FM broadcast radio tuners delivering the entire FM tuner from antenna input to audio output in 100% CMOS. Using a digital architecture, the tuners improve performance while reducing component count. The Si4700 FM broadcast radio tuner integrates selectivity filtering, automatic gain control, frequency synthesizer and audio processing. The Si4700 requires one external supply bypass capacitor and can be implemented in less than 20 mm² board space. The company also offers the Si4701, incorporating a digital pre-processor for the European Radio Data System (RDS) and the U.S. Radio Broadcast Data System (RBDS), enabling data such as the station ID and song name to be displayed to the user.
