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.
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 500
ms) 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
timing.
Data can be read out starting with the backward-
protection block data after a synchronization reset.
Bit slip detection and correction
Low spurious radiation
Fully adjustment free
Operating power-supply voltage: 4.5 to 5.5 V
Operating temperature: –40 to +85°C
