Description

The TDA7331, an improved version of TDA7330B, 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.
The TDA7331 is made up of two sections: a cas-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 decoder.
Outputs for RDS signal qualityand ARI indication are also present.
