CMOS IC

LC72720Y, 72720YV

Single-Chip RDS

Signal-Processing System IC

Overview

Features

The LC72720Y and LC72720YV 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.

• 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.

• Fully adjustment free.

Functions

• Low voltage (supply voltage: 3.0 V min) type.

• Operating power-supply voltage: 3.0 to 3.6 V

• Operating temperature: –40 to +85°C

• Band-pass filter: Switched capacitor filter (SCF)

• Demodulator: RDS data clock regeneration and

demodulated data reliability information

• Package: DIP24S, SSOP30

• 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)

•
