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

■ VCO and programmable divider for “world

receiver”

■ Programmable controlled IF-gain stage

■ High performance fast PLL for RDS-system

■ Electronic alignment for the preselection

stages

■ All functions bus-controlled

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,

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.
