The Si4709 incorporates a digital processor for the European Radio Data System (RDS) and the US Radio Broadcast Data System (RBDS) including all required symbol decoding, block synchronization, error detection and error correction functions. RDS enables data such as station identification and song name to be displayed to the user. The Si4709 offers both a detailed RDS view and a standard view, allowing adopters to selectively choose granularity of RDS status, data, and block errors. Si4709 software is backwards compatible to the proven Si4701/03, adopted by leading cell-phone, PND and MP3 manufacturers world-wide.
he Si4708/09 devices' high level of integration and complete FM system increase quality to manufacturers, improve device yields and simplify device manufacturing and final testing.
