Overview
The LC7074 and the LC7074M are ICs for the RDS (radio
data system) implemented by the EBU (European Broad-
casting Union) and the RDBS (radio broadcast data sys-
tem) implemented by the NRSC (National Radio System
Committee) in the USA.
RDS and RBDS are standards that allow data to be broad-
cast multiplexed with other FM broadcasts. When combined
with an IC in the LA2230 series, the LC7074/M synchro-
nizes with data multiplexed in an FM broadcast and de-
tects and corrects errors in that data. The synchronized data
is output as a serial signal which can then be decoded and
processed on the system control microprocessor.
Functions
Group synchronization.
RDS group synchronization.
MMBS/RDS group synchronization.
Error detection and correction.
Error detection function enable/disable selection.
Serial data output.
Serial data clock polarity selection.
Data block start signal output.
Features
System that decode, synchronize and detect and correct
errors can easily be constructed by combining the
LC7074/M with an LA2230 series product.
Reduces overhead in the microprocessor that decodes and
processes the RDS or MMBS/RDS data.
