LC72722M
Single-Chip RDS Signal-Processing System LSI
Ordering number : ENN6123A
CMOS IC
LC72722, 72722M, 72722PM
Overview
The Lc72722 And Lc72722m, Lc72722pm Are Singlechip 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 Backwardprotection 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
Package: LC72722 : DIP24S
