Connecting Everyone and Everything, All the Time

Skyworks is pleased to introduce the Si469xx Automotive Digital Radio Coprocessor Family for HD Radio™, DAB/DAB+, DRM, CDR.

The Si469xx family of automotive digital radio coprocessors offers an optimally balanced combination of integration, flexibility and cost, and is designed to operate with Skyworks’ Si479xx family of Hybrid Software Defined Radio (SDR) tuners to achieve a complete digital radio receiver. The new Si469xx product family can demodulate and decode up to four digital radio channels supporting HD Radio™, DAB/DAB+, DRM (for AM and FM), and CDR, providing unmatched performance and scalability for future in-vehicle infotainment (IVI) systems.

 The Si469xx product family supports advanced capabilities such as Maximal Ratio Combining (MRC) and seamless linking of digital radio, analog radio and Internet Protocol content. With its integrated customer-programmable microcontroller (MCU), the Si469xxC  can significantly reduce bill of materials (BOM) costs by eliminating the need for an external MCU and its support components. Software design is simplified through several improvements, including a Demod/Tuner Manager that relieves system developers from having to program low-level radio control functions.

“Building on the unparalleled scalability of Skyworks’ automotive radio product portfolio with the added benefits of improved performance, lower system cost and ease of use, the Si469xx family of products enhances our ability to address the needs of future IVI systems by delivering best-in-class capability, flexibility and affordability to our customers,” said Juan Revilla, vice president and general manager of broadcast products at Skyworks. “Along with our family of Si479xx Hybrid SDR tuners, this new family of digital radio coprocessors enhances our overall automotive product portfolio and bolsters our strategy in this key secular growth market. Skyworks is strongly positioned to address RTM, SDR and head unit automotive radio implementations.”
