TDA7479

Single chip RDS demodulator + filter

Features

■ Very high RDS demodulation quality with

improved digital signal processing

■ High performance, 57 kHz bandpass filter

(8 order)

SO16

■ FIlter adjustment free and without external

components

■ Purely digitaL RDS Demodulation without

external components

■ ARI (SK indication) and RDS signal quality

output

TSSOP16

■ 4.332 MHz crystal oscillator

(8.664 and 17.328 MHz optional)

■ Low noise CMOS technology

■ Low radiation

The device is made up of two sections: a

cascaded antialiasing + switched capacitors 8

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.

Description

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.

Outputs for RDS signal quality and ARI indication

are also present.
