Description

The Si4749 is a 100% CMOS receiver integrated

circuit (IC), offering the full receive functionality from

antenna to RDS/RBDS* data for use in the

automotive and personal navigation markets. It is an

ideal companion RDS background data receiver for

Traffic Message Channel (TMC) and Open Data

Applications (ODA) applications frequently used in

conjunction with GPS functionality or as an alternate

frequency (AF) scanner in automotive radios. It offers

European RDS* and the North American RBDS. It

includes demodulation, symbol decoding, advanced

error correction, detailed visibility to block-error rates

(BLER), and decoder reliability, synchronization

status, and times. The Si4749 provides complete,

decoded, and error-corrected RDS groups, up to 25

groups at a time with associated BLER.

The Si4749 incorporates a high performance RDS

decoder based on patented methodologies, and

delivers excellent RDS sensitivity performance,

synchronization to RDS at high BLER levels, and

RDS data decoding with superior decoder reliability.

The Si4749 draws on Silicon Laboratories' broadcast

audio and corresponding patent portfolio using a

digital low intermediate frequency (low-IF) receiver

architecture

broadcast audio receivers shipped worldwide. The

low-IF architecture allows the Si4749 to deliver

superior performance while integrating the great

majority

competing solutions.

The Si4749 is feature-rich, providing both highly
