TDA7512F

FM car-radio tuner IC with intelligent selectivity system (ISS)

Features

FM part

■ RF AGC generation by RF and IF detection

■ I/Q mixer for 1st FM IF 10.7 MHz with image

rejection

■ 2 programmable IF-gain stages

■ Mixer for 2nd IF 450 kHz

■ Internal 450 kHz bandpass filter with three

bandwidths controlled by ISS

■ Fully integrated FM-demodulator with noise

cancellation

Additional features

■ VCO for world tuning range

■ High performance fast PLL for RDS-system

■ IF counter with search stop signal

■ Quality detector for level, deviation, adjacent

channel and multipath

■ Quality detection informations as analog

signals external available

■ ISS (intelligent selectivity system) for

cancellation of adjacent channel and noise

influences

■ Adjacent channel mute

■ Fully electronic alignment

■ All functions I2C bus controlled

Description

The TDA7512F is a high performance tuner circuit

for FM car-radio. It contains mixer, IF amplifier,

demodulator, quality detection, ISS filter and PLL

synthesizer with IF counter on a single chip. Use

of BiCMOS technology allows the implementation

of several tuning functions and a minimum of

external components.
