Si4683-A10
Single-Chip, AM/FM/HD Radio Receiver
Description
The Si4683 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 Si4683 is compatible with the iBiquity Digital and
NRSC-5 standards for AM/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 Si4683
is capable of tuning HD Radio™ reception to cover
additional AM/FM frequencies for future IBOC adoption
outside of North America. The Si4683 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 Si4683 additionally supports worldwide AM/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.
