Description

The Si474x receiver family applies 100% RF CMOS

technology to bring digital low-IF radio technology to the

automotive receiver market. The Si474x receiver family

builds on Silicon Laboratories’ highly successful broadcast

audio radio products, offering design simplicity, unmatched

integration, programmability, and automotive quality and

reliability.

The Si474x receiver family supports world-wide FM bands

from 64–108 MHz and AM bands from 520–1710 kHz. The

Si474x supports AM/FM, weather band, shortwave, and

longwave radio bands. All odd-numbered part numbers in

the family support international RDS/RBDS protocols.

The Si474x family leverages Silicon Laboratories’ patented

digital architecture, delivering superior RF performance

and interference rejection. The proven digital radio

technology provides excellent sensitivity in weak signal

environments, and superb selectivity and inter-modulation

immunity in strong signal environments.

The solution offers programmable AM/FM channel spacing

and filters, 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 features such as noise blanking,

programmable soft mute, and multi-path detection and

mitigation.

The Si474x receiver system has a minimal bill of materials

requiring a small amount of board space. The high level of

integration provides a complete, tested broadcast audio

receiver that is ideal for primary automotive radio receivers.
