TDA7529

RF front-end for AM/FM DSP car-radio with IF sampling

Features

■ Fully integrated VCO for world tuning

■ High performance PLL for fast RDS system

■ I/Q mixer for FM IF 10.7 MHz with image

rejection and integrated LNA

■ I/Q mixer for AM IF 10.7 MHz up conversion

with high dynamic range

■ Integrated balun, which allows saving of

external mixer tank

■ RF AGC, IF AGC, DAGC

■ Low noise IF amplifier with switched wide

dynamic AGC range

■ IF switch for FM / AM / IBOC

■ Electronic alignment for the preselection

stages

■ I2C/SPI controlled

■ Single 5 V supply

■ Alternative frequency control signals to DSP

Description

The front-end is a high performance tuner circuit

for AM/FM - DSP car-radios with 10.7 MHz 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.
