TDA7330B
DESCRIPTION
The TDA7330B is a RDS demodulator. It recovers the additional inaudible RDS information which is transmitted by FM radio broadcasting stations. The output data signal (RDDA) and clock signal (RDCL) can be further processed by a suitable RDS decoder (microprocessor). The device operates in accordance with the EBU (European Broadcasting Union) specifications. The IC includes a 2nd order antialiasing input fil BLOCK DIAGRAM
