LQFP64

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.
