Si4688-A10
Single-Chip, FM/HD/DAB/DAB+ Radio Receiver
Description
The Si4688 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 Si4688 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 Si4688
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 Si4688 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 Si4688 delivers DAB and
DAB+ via an integrated source decoder that supports both
MPEG Audio Layer 2 (DAB) and HE-AAC V2 (DAB+). The
Si4688 supports data services such as Dynamic Labels,
Intellitext, Electronic Program Guide (EPG), Slideshow,
and Journaline® with the appropriate external decoders.
