Si4689-A10 Single-Chip, AM/FM/HD/DAB/DAB+ Radio Receiver Description Features The Si4689 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 Si4689 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 Si4689 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 Si4689 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 Si4689 delivers DAB and DAB+ via an integrated source decoder that supports both MPEG Audio Layer 2 (DAB) and HE-AAC V2 (DAB+). The Si4689 supports data services such as Dynamic Labels, Intellitext, Electronic Program Guide (EPG), Slideshow, and Journaline® with the appropriate external decoders.
