Description
●The Si4702/03-C19 extends Silicon Laboratories Si4700/01 FM tuner family and further increases the ease and
●attractiveness of adding FM radio reception to mobile devices through small size and board area, minimum
●component count, flexible programmability, and superior, proven performance. The Si4702/03 leverage Silicon Laboratories" highly successfuland patented Si4700/01 FM tuner, and are pin and software compatible to existing Si4700/01 FM tuner designs. The Si4702/03 benefits from proven digital integration and 100% CMOS process technology, resulting in a completely integrated solution.
