CMOS LSI  
LC72720, 72720M  
Single-Chip RDS  
Signal-Processing System LSI  
Preliminary  
Overview  
Package Dimensions  
unit: mm  
The LC72720 and LC72720M are single-chip system LSIs  
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 LSIs 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.  
3067-DIP24S  
[LC72720]  
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  
SANYO: DIP24S  
unit: mm  
3045B-MFP24  
[LC72720M]  
• 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  
SANYO: MFP24  
• Operating power-supply voltage: 4.5 to 5.5 V  
• Operating temperature: –40 to +85°C  
• Package: DIP24S, MFP24

CCB is SANYO’s original bus format and all the bus  
addresses are controlled by SANYO.
