This IC include band-pass filter, demodulator, and data buffer 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: 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.
