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).

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

• Synchronous demodulator for 57 kHz modulated RDS signals

• Selectable 4.332/8.664 MHz crystal oscillator with variable

dividers

• Clock regeneration with lock on bi-phase data rate

• Bi-phase symbol decoder with integrate and dump functions

• Differential decoder

• Signal quality detector

• Subcarrier output.
