17-12-2021 | Skyworks | Automotive Technologies

Skyworks has released the Si4694 digital radio coprocessor for DRM for AM radio reception in automotive infotainment systems and car radios. Created to work with its Si479xx family of automotive radio tuners, the new device offers a new level of performance and power efficiency with an extremely low system BOM.

The device is part of the Falcon family of automotive digital radio coprocessors. It offers demodulation and source decoding of DRM for AM signal delivering audio and data. It supports all operating modes of the DRM for AM digital radio standard (Modes A to D). It is a highly integrated device that needs only a few external components. The device generates its internal clocking from an external crystal utilising an integrated oscillator or an external reference clock and supports a selectable host-control interface (SPI or I2C). Together with the company’s Si479xx tuners, it offers a complete and cost-effective DRM for AM solution.
