SAA6581T

INTEGRATED CIRCUITS DATA SHEET SAA6581T RDS/RBDS demodulator Product specification File under Integrated Circuits, IC01 2001 May 07 Philips Semiconductors Product specification RDS/RBDS demodulator FEATURES Integrated switched capacitor filter Demodulates European Radio Data System (RDS) or the USA Radio Broadcast Data System (RBDS) signals Oscillator frequencies: 4.332 or 8.664 MHz Integrated ARI clamping CMOS device Single supply voltage: 5 V Extended temperature range: −40 to +85 °C Low number of external components. GENERAL DESCRIPTION The RDS/RBDS demodulator is a CMOS device with integrated filtering and demodulating of RDS/RBDS signals coming from a multiplexed input data stream. Data signal RDDA and clock signal RDCL are provided as outputs for further processing by a suitable microcomputer, for example CCR921 and CCR922. The SAA6581T replaces SAA6579 in function and pin-compatibility.
