SANYO 单芯片RDS信号处理芯片
Single-Chip RDS Signal-Processing System LSI
Overview
The LC72722 and LC72722M, LC72722PM 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)
封装：MFP24
