Description
The Si476x radio receiver family employs 100% RF CMOS
technology to bring outstanding receiver performance to
the automotive infotainment industry, which demands high
performance and quality.
The Si476x receiver family supports worldwide FM and AM
radio reception. Additional variants support weather band,
shortwave, longwave frequencies, and dual antenna FM
phase diversity reception.
The Si476x incorporates a digital processor for the
European Radio Data System (RDS) and the North
American Radio Broadcast Data System (RBDS) including
all required symbol decoding, block synchronization, error
detection, and error correction functions. All odd-numbered
variants in the family support AM/FM HD Radio channel
reception with digital (I
interface to a HD Radio demodulator/decoder.
The family leverages Silicon Laboratories’ patented digital
architecture, delivering superior RF performance and
interference rejection. The proven digital techniques
provide excellent sensitivity in weak signal environments,
and superb selectivity and inter-modulation immunity in
strong signal environments.
The solution offers dynamic AM/FM channel bandwidth
control, auto-calibrated digital tuning, and proven AM/FM
seek functionality based on multiple signal quality and
band parameters. The family offers highly flexible and
advanced audio processing including AM/FM noise
blanking,
mitigation, FM stereo-mono blend, and FM hi-cut. In
addition, the Si476x provides an integrated clock oscillator
or accepts a reference clock and an I
control interface. The Si476x receiver system specifies a
minimal bill of materials, resulting in a very small board
space requirement and making the solution ideal for any
automotive application from single tuner radios to multiple
tuner radios addressing
scanning.
