Description
The TDA7540 is a high performance tuner circuit
for AM/FM car radio. It contains mixer, IF
amplifier, demodulator for AM and FM,
stereodecoder, 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.
