Overview
The LC72722 and LC72722M, LC72722PM are single chip system ICs 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) RDBS (Radio Broadcast Data System) standard. These ICs 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.

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.
