Overview
The LC72720N and LC72720NM 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 microcontroller 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.
Fully adjustment free
Operating power-supply voltage: 4.5 to 5.5 V
Operating temperature: –40 to +85°C
