Overview

The Si475x radio receiver family employs RF CMOS technology to bring outstanding radio receiver performance and automotive quality to the automotive infotainment industry. The Si475x family supports worldwide FM, AM, shortwave, longwave, and weatherband radio reception. The Si475x receiver system specifies a minimal bill of materials, resulting in a very small board space requirement, making the solution ideal for any automotive application from single tuner radios to multiple tuner radios addressing companion TMC/AF reception/scanning.The monolithic IC incorporates a digital signal processor and microcontroller, leveraging Silicon Laboratories patented and proven low-IF architecture, delivering superior RF performance and interference rejection, as well as excellent sensitivity in weak signal environments and superb selectivity and inter-modulation immunity in strong signal environments. The device performs signal conditioning with dynamic AM/FM channel bandwidth control, a comprehensive set of weak signal processing engines, auto-calibrated digital tuning, and proven AM/FM seek functionality based on multiple signal quality and band parameters. The device offers world-class performance for complete Radio Data Service (RDS) decoding, synchronization, error detection and correction. The device is also completely configurable, allowing raw RDS data if so desired.The part provides an integrated clock oscillator or accepts a reference clock and an I2C-compatible 2-wire control interface. Bostock Electronics is an authorized Silicon Labs distributor.
