Auto AM/FM RX IC offers RDS decoder

Implemented in CMOS, the Si474x automotive AM/FM radio receiver IC family supports worldwide radio band requirements, including FM, FM radio data system (RDS), AM, long wave (LW), short wave (SW), and weather bands. The part also integrates an RDS decoder.

Measuring 4 x 4 mm, the device supports integrated algorithms for fully customizable multipath detection and mitigation, impulse noise event detection and blanking, and advanced audio behavior in the presence of blockers, fading signals, or other adverse radio environments. (Si4743, which supports AM/FM, FM RDS/RBDS, LW, and weather band, from $7.48 ea/10,000; evaluation board, $150 — 4th qtr.)
