RADIO DATA SYSTEM (RDS)

DEMODULATOR

DESCRIPTION

The integrated CMOS circuit SC6579 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).
