GENERAL DESCRIPTION
The integrated CMOS circuit SAA6579 is an RDS
demodulator. It recovers the additional inaudible RDS
information which is transmitted by FM radio broadcasting.
The data signal RDDA and the clock signal RDCL are
provided as outputs for further processing by a suitable
decoder (microcomputer).
The operational functions of the device are in accordance
with the “CENELEC EN 50067” .
