Single chip RDS demodulator + filter
Package
SO16
Rev 7
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.
Outputs for RDS signal quality and ARI indication
are also present.
