The Si474x from Silicon Laboratories is a fully integrated automotive AM/FM radio receiver integrated circuit. Based on Silicon's digital low-IF architecture, the Si474x family is the first automotive AM/FM receiver to be implemented in a complementary metal oxide semiconductor, says the company, cost-effectively meeting automotive-grade radio performance requirements while reducing customers' time to market. According to the company, the 4 x 4 mm (0.157 x 0.157 in) Si474x offers a reduction of external component count and associated cost more than 40% compared to competitive solutions. It has also eliminated the need for manual alignment during manufacturing. Supporting worldwide radio band requirements, the Si474x family provides customers the flexibility to support a variety of worldwide needs with a single design.
