Overview
The LC72720YV 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 500ms) 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
