Ordering number : ENN6488
CMOS IC
LC72720Y, 72720YV
Single-Chip RDS
Signal-Processing System IC
Overview
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.
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.
• Fully adjustment free.
• 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
• Package: DIP24S, SSOP30
• CCB is a trademark of SANYO ELECTRIC CO., LTD.
• CCB is SANYO’s original bus format and all the bus
addresses are controlled by SANYO.
Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.
SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other
parameters) listed in products specifications of any and all SANYO products described or contained
