SAA6579, Radio Data System RDS demodulator

INTEGRATED CIRCUITS DATA SHEET SAA6579 Radio Data System (RDS) demodulator Product speciﬁcation Supersedes data of January 1994 File under Integrate.
SAA6579 The integrated CMOS circuit SAA6579 is an RDS demodulator.

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

Applications

* It contains a 57 kHz bandpass filter and a digital demodulator to regenerate the RDS data stream out of the multiplex signal (MPX). Filter part The MUX signal is band-limited by a second-order anti-aliasing-filter and fed through a 57 kHz band-pass filter (8th order band-pass filter with 3 kHz band
