LC72725KM,
LC72725KV
Overview
The LC72725KM and LC72725KV are 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) RBDS (Radio
Broadcast Data System) standard. These ICs include band-pass filter, demodulator,and data buffer RAM on chip. RDS
data can be read out from this on-chip memory by external clock input in slave operation mode.
Functions
Bandpass filter: Switched capacitor filter (SCF)
RDS Demodulation: 57KHz carrier and RDS data clock regeneration, biphase decode, differential decode.
Buffer RAM: 128 bit (about 100ms) can be restored in the on-chip data buffer RAM.
Data output: Master or slave output mode can be selected.
RDS-ID: Detect RDS signal which can be reset by RST signal input.
Standby control: Crystal oscillator can be stopped.
