Description
The front-end is a high performance tuner circuit
for AM/FM - DSP car-radios with 10.7MHz IF
sampling. It contains mixer and IF amplifiers for
AM and FM, fully integrated VCO and PLL
synthesizer on a single chip. Use of BiCMOS
technology allows the implementation of several
tuning functions and a minimum of external
components.
