Product Summary

The TDA7479 recovers the additional inaudible 
RDS information which is transmitted by FM radio 
broadcasting stations and operates in accordance 
with the EBU (European Broadcasting Union) 
specifications.
The device is made up of two sections: a 
cascaded antialiasing + switched capacitors 8
th
bandpass filter for precise RDS band selection 
and a demodulating section that performs the 
extraction od RDS data stream (RDDA) and clock 
(RDCL), to be further processed by a suitable 
RDS decoder.

Features

improved digital signal processing
■ High performance, 57 kHz bandpass filter
(8
th
 order)
■ FIlter adjustment free and without external 
components
■ Purely digitaL RDS Demodulation without 
external components
■ ARI (SK indication) and RDS signal quality 
output
■ 4.332 MHz crystal oscillator
(8.664 and 17.328 MHz optional)
■ Low noise CMOS technology
■ Low radiation
