TDA7515
RF front-end for AM/FM-DSP car radios with IF sampling
Features
■ RF AGC generation by RF and IF detection
■ I/Q Mixer for FM IF 10.7MHz with image
rejection and programmable IF tank adjust for
FM and AM
■ Preamplifier and mixer for IF 10.7MHz AM
upconversion

Description
The front-end is a high performance tuner circuit
for AM/FM - DSP car radios with 10.7MHz - IF
sampling.
LQFP44
It contains mixer and IF amplifiers for AM and FM,
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.
