TDA7529 Datasheet PDF - ST Microelectronics

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 singlechip. Use of BiCMOS technology allows the implementation of several tuning functions and a minimum of external components.

●Features

●■ Fully integrated VCO for world tuning

●■ High performance PLL for fast RDS system

●■ I/Q mixer for FM IF 10.7MHz with image rejection and integrated LNA

●■ I/Q mixer for AM IF 10.7MHz 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 5v SUPPLY

●■ Alternative frequency control signals to DSP
