TDA7330B

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 TDA7330B operates in accordance with the EBU (European Broadcasting Union) specifications.

The TDA7330B includes a 2nd order antialiasing input filter, a 57KHz switched capacitor band pass filter, a smoothing filter and cross detector, a bit rate clock recovery circuit, a 57KHz PLL, BI-PHASE PSK decoder, differential decoding circuit, ARI indication and RDSsignal quality output.
