FEATURES
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.
