DESCRIPTION  
caded antialiasing + switched capacitors band-  
pass filter for precise RDS band selection and a  
demodulating section that performs the extraction  
od RDS data stream (RDDA) and clock (RDCL),  
to be furher processed by a suitable RDS de-  
coder.  
The TDA7331, an improved version of  
TDA7330B, recovers the additional inaudible  
RDS information which is transmitted by FM radio  
broadcasting stations and operates in accord-  
ance with the EBU (European Broadcasting Un-  
ion) specifications.  
Outputs for RDS signal quality and ARI indication  
are also present.  
The device is made up of two sections: a cas-
