Automotive Digital Radio Coprocessors: Si469xx Datasheet

The Si469xx product family can demodulate and decode up to four digital radio channels, 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.
