Description
The Si4836 is the high performance receiver function from antenna input to audio
output. The Si4836 extends Silicon Laboratories multi-band tuner family, and
further increases the ease and attractiveness of design radio reception to audio
devices through small size and board area, minimum component count, and
superior, proven performance. Si4836 enhances the FM and SW band coverage,
further supports China TV channels audio reception in FM band. The Si4836
removes any requirements for manually tuning components during the
manufacturing process. The receiver has very low power consumption, runs off
two AAA batteries, and delivers the performance benefits of digital tuning to the
analog radio market.
