Si4682-A10 Single-Chip, FM/HD Radio Receiver - 1

Si4682-A10 Single-Chip, FM/HD Radio Receiver Description The Si4682 single-chip digital receiver is one member of a family of 100% CMOS digital radio broadcast receiver ICs from Silicon Labs. The Si468x family offers a complete and cost-effective digital radio solution integrating the RF tuner, baseband and audio processing on a single die. The high level of integration provides significant customer benefits compared to traditional digital radio solutions including a reduction in system implementation complexity, validation and testing, and improved reliability and manufacturability. The Si4682 is compatible with the iBiquity Digital and NRSC-5 standards for FM In-Band-On-Channel (IBOC) digital radio broadcasting, integrating digital channel demodulation and decoding functions, along with audio decoding and IBOC analog-digital blend. The Si4682 is capable of tuning HD Radio™ reception to cover additional FM frequencies for future IBOC adoption outside of North America. The Si4682 additionally supports IBOC multicasting, as well as the full-range of HD Radio data services, such as PSD (Program Service Data), Artist Experience, iTunes® Tagging, Bookmark and real-time traffic, with the appropriate external decoders. The Si4682 additionally supports worldwide FM radio reception and incorporates a fully integrated decoder for the European Radio Data System (RDS) and the North American Radio Broadcast Data System (RDBS) including all required symbol decoding, block synchronization, error detection, and error correction functions.
