Si4622

Si462x Digital Data Receivers

Si4622 single-chip digital data receivers are a 100% CMOS digital radio broadcast receiver IC for automotive infotainment systems, enabling HD Radio/DAB/DAB+ services reception, and providing significant advances in size, power consumption, and performance.  Si4622 data receivers offer a complete and cost-effective platform to support global analog and digital AM, FM, and VHF band III radio standards by integrating multiband RF tuner, demodulator, and channel decoder on a single die. The high level of integration and complete system production test simplifies design-in, increases system quality, and improves reliability and manufacturability. 

Supporting worldwide analog AM and FM radio reception, Si4622 devices incorporate a fully integrated decoder for the European Radio Data System (RDS) and the North American Radio Broadcast Data System (RDBS). Functions include all required symbol decoding, block synchronization, error detection, and error correction. 

The digital data receivers are built on proven and patented digital low intermediate frequency (low-IF) receiver architecture, delivering superior RF performance and interference rejection. The solution offers auto-calibrated digital tuning, and proven AM/FM seek functionality based on multiple signal quality and band parameters. In addition, Si4622 devices provide an integrated clock oscillator or accept a reference clock and support a selectable control interface (SPI or I²C).
