DESCRIPTION
The frontend is a high performance tuner circuit for
AM/FM - DSP carradios with 10.7MHz - IF sampling.
It contains mixer and IF amplifiers for AM and FM,
VCO and PLL synthesizer on a single chip.
Use of BICMOS technology allows the implementa-
tion of several tuning functions and a minimum of ex-
ternal components.
