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.

DIP-16

The data signal RDDA and the clock signal RDCL are provided

as outputs for further processing by

(microcomputer).

FEATURES

• Anti-aliasing filter (2nd order)

• Integrated 57 kHz band-pass filter (8th order)

• Reconstruction filter (2nd order)

• Clocked comparator with automatic offset compensation

• 57 kHz carrier regeneration
