... CRYSTAL OSCILLATOR (8.664MHz OPTIONAL) LOW NOISE MIXED BIPOLAR/CMOS TECH- NOLOGY DESCRIPTION The TDA7330B is a RDS demodulator. It recov- ers 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) ...
