Sync and Error Detection & Correction ICs
for RDS
Overview
The LC7070N, LC7070NM and LC7071NM CMOS Sync
and Error Detection & Correction ICs are designed for use
in the RDS (Radio Data System) implemented by the EBU
(European Broadcasting Union). RDS is used to multiplex
various data on the FM broadcast signal.
When used with the SANYO LA2231 RDS Decoder IC, a
simplified processor can be designed for demodulation, syn-
chronization, and error detection & correction of the data
multiplexed on the FM broadcast, significantly reducing
the front-end load on the system controller.
The data with adjusted sync are obtained as a serial signal
output which can be passed to the system controller for
processing.
LC7070 × × devices are fabricated using a low-power
CMOS process and are available in 18-pin plastic DIPs and
MFPs with and without output pull-ups.
