LC72720YVS
RDS/RBDS Single-chip Signal
Processor IC
Overview
The LC72720YVS is a single-chip system IC that implement the signal
processing required by the European Broadcasting Union RDS (Radio
Data System) standard and by the US NRSC (National Radio System
Committee) RBDS (Radio Broadcast Data System) standard. This IC
include band-pass filter, demodulator, synchronization, and error
correction circuits as well as data buffer RAM on chip and perform
effective error correction using a soft-decision error correction technique.
Functions
Band-pass filter : switched capacitor filter (SCF)
Demodulator : RDS data clock regeneration and demodulated data
reliability information
Synchronization : Block synchronization detection
(with variable backward and forward protection conditions)
Error correction : Soft-decision/hard-decision error correction
Buffer RAM : Adequate for 24 blocks of data (about 500 ms) and flag
memory
Data I/O : CCB* interface (power on reset)
Features
Error correction capability improved by soft-decision error correction
The load on the control microprocessor can be reduced by storing
decoded data in the on-chip data buffer RAM.
Two synchronization detection circuits provide continuous and stable
detection of the synchronization.
Data can be read out starting with the backward-protection block data
after a synchronization reset.
Fully adjustment free
