Si4749
High-Performance FM RDS/RBDS Data Receiver/
Alternate Frequency Scanner
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
a fully-integrated advanced decoder for the
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 proven by hundreds of millions
broadcast audio receivers shipped worldwide. The
low-IF architecture allows the Si4749 to deliver
superior performance while integrating the great
majority of external components required by
competing solutions.
The Si4749 is feature-rich, providing both highly
automated performance, according to Silicon
Laboratories' recommended settings, or extensive
programmability and flexibility for customized system
performance. The part accepts programmable
reference clock values. The Si4749 offers several
modes of operation for various applications which
provide more or less visibility to the RDS status and
group data. The Si4749 is offered in a compact
4 x 4 x 0.85 mm 24-pin Quad Flat No-Lead (QFN)
package.
*Note: The term “RDS” will be used to mean “RDS/
RDBS” throughout this document.
