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
