Overview

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 (I2S) baseband I/Q outputs for 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, programmable soft mute, FM multi-path 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 I2C-compatible, 2-wire 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 companion TMC/AF reception/scanning.
