Si463x-A10 Data Short Single-Chip, AM/FM/HD/DAB/DAB+ Radio Receiver Family The Si463x single-chip digital receiver is a family of 100% CMOS digital radio broadcast receiver ICs from Silicon Labs. The Si463x 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 Si463x is compatible with the iBiquity Digital and NRSC-5 standards for 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 Si463x supports IBOC multicasting, as well as the full range of HD Radio data services, such as PSD, Artist Experience, iTunes Tagging, Bookmark and real-time Traffic, with the appropriate external decoders. The Si463x also offers VHF Band III (168-240 MHz) reception capability and is fully compliant with ETSI EN 300 401 and ETSI TS 102 563. The Si463x delivers DAB and DAB+ via an integrated source decoder that supports both MPEG Audio Layer 2 (DAB) and HE-AAC V2 (DAB+). The Si463x supports data services such as Dynamic Labels, Intellitext, Electronic Program Guide (EPG), Slideshow, and Journaline with the appropriate external decoders.
