Features

Applications

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.
