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.
