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. • Fully adjustment free • Low Voltage Specifications Absolute Maximum Ratings at Ta = 25°C, VSSd = VSSa = 0V Parameter Symbol Pin Name Conditions Ratings Unit Maximum supply voltage VDD max VDDd, VDDa * VDDa≤VDDd+0.3V -0.3 to +6.5 V VIN1 max TEST, MODE, XIN, RDCL, RST -0.3 to VDDd+0.3 V Maximum input voltage VIN2 max MPXIN, CIN -0.3 to VDDa+0.3 V VO1 max RDS-ID(READY) -0.3 to +6.5 V VO2 max XOUT, RDDA, RDCL -0.3 to VDDd+0.3 V Maximum output voltage VO3 max FLOUT -0.3 to VDDa+0.3 V IO1 max XOUT, FLOUT, RDDA, RDCL +2.0 mA Maximum output current IO2 max RDS-ID(READY) +8.0 mA * VDDa≤VDDd+0.3V Continued on next page.
