Introduction

The TDA7478 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 device is made up of two sections: a cascaded antialiasing + switched capacitors 8th bandpass filter for precise RDS band selection and a demodulating section that performs the extraction of RDS data stream (RDDA) and clock (RDCL), to be further processed by a suitable RDS decoder. Output for RDS signal quality is also present.
