Description
The TDA7512F is a high performance tuner circuit
for FM car-radio. It contains mixer, IF amplifier,
demodulator, quality detection, ISS filter and PLL
synthesizer with IF counter on a single chip. Use
of BiCMOS technology allows the implementation
of several tuning functions and a minimum of
external components.
