Ordering number:ENN 3932 CMOS IC LC7073, 7073M Error Detection and Correction ICs for RDS Demodulators Preliminary Overview The LC7073 and LC7073M are error detection and correction ICs that provide an easy interface to the LA2230 and LA2231 radio data system (RDS) demodulators.

Both devices incorporate an on-chip oscillator that connects directly to an external ceramic resonator.

The LC7073 and LC7073M provide group synchronization, selectable error detection and correction, output clock
