AM/FM Receiver IC Outfits Any Consumer Device

Enabling AM/FM capability for any consumer device, the Si473x debuts as the market's first fully integrated AM/FM radio receiver from antenna input to audio output on a single monolithic IC. The chip requires only two external components in 0.15 cm² of board space as opposed to more than 50 components and 10 cm² of board space for existing topologies. Setting another benchmark, the Si473x claims to be the only AM/FM receiver that does not need manual alignment. The device supports a wide variety of antennas with an on-chip varactor and auto calibration. Additionally, the Si4731 is reportedly the only AM/FM receiver to include support for the European Radio Data System (RDS) and the U.S. Radio Broadcast Data System (RBDS). Samples of the Si4730 and Si4731 are available in 20-pin, 3 mm x 3 mm QFN packages. Prices are $4.87 and $5.53 each/10,000, respectively. An evaluation board is available for $150.
