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.
