DESCRIPTION
The TDA7479 recovers the additional inaudible
RDS informationwhich is transmittedby FM radio
broadcasting stations and operates in accord-
ance with the EBU (European Broadcasting Un-
ion) specifications.
BLOCK DIAGRAM AND TEST CIRCUIT
The device is made up of two sections: a cas-
caded antialiasing + switched capacitors band-
pass filter for precise RDS band selection and a
demodulatingsection that performs the extraction
od RDS data stream (RDDA) and clock (RDCL),
to be furher processed by a suitable RDS de-
coder.
Outputs for RDS signal quality and ARI indication
are also present.
