The TDA7478 recovers the additional inaudible RDS
information which is transmitted by FM radio broad-
casting stations and operates in accordance with the
DESCRIPTION
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 pro-
cessed by a suitable RDS decoder.
Output for RDS signal quality is also present.
