Digital radio coprocessors in Skyworks’ Si469x sequence demodulate and decode as much as 4 digital radio channels in automotive infotainment programs. The units assist HD Radio, DAB/DAB+, DRM for AM and FM, and CDR, offering design flexibility and scalability.
Si469xx coprocessors are optimized to work with the corporate’s Si479xx sequence of hybrid software-defined radio (SDR) tuners to kind a digital radio receiver. They provide maximal ratio combining (MRC) and seamless linking of digital radio, analog radio, and Web Protocol (IP) content material.
With their built-in customer-programmable MCU, the Si469xx coprocessors cut back BOM prices by eliminating the necessity for an exterior MCU and its assist elements. An built-in Demod/Tuner Supervisor controls tuner and channel processing, relieving system builders from having to program low-level radio management features.
In keeping with Skyworks, the usage of separate tuner and coprocessor ICs not solely achieves an optimum steadiness between partitioning and integration, but additionally helps cut back thermal points related to distant tuner module (RTM) designs. It additionally affords scalability to handle a number of areas and efficiency factors.
Manufacturing launch of the Si469xx sequence of digital radio coprocessors is predicted within the first half of 2024. Contact your native Skyworks gross sales or distributor for samples.
