TDA7705

Highly integrated tuner for AM/FM car radio

Features

■ Fully integrated VCO for world tuning

■ High performance PLL for fast RDS system

■ AM/FM mixers with high image rejection

■ Integrated AM-LNA and AM-PINDIODE

■ Automatic self alignment for preselection and

image rejection

■ Digital IF signal processing, high performance

LQFP64

and drift-free

■ Integrated IF-filters with high selectivity, high

dynamic range and adaptive bandwidth control

■ RDS demodulation with group and block

synchronization

It contains mixers and IF amplifiers for AM and

FM, fully integrated VCO and PLL synthesizer,

IF-processing including adaptive bandwidth

control, stereo decoder and RDS decoder on a

single chip.

■ High performance stereodecoder with

noiseblanker

■ I C/SPI bus controlled

■ Single 5 V supply

■ LQFP64 package

The utilization of digital signal processing results

in numerous advantages against today's tuners:

very low number of external components, very

small space occupation and easy application,

very high selectivity due to digital filters, high

flexibility by software control and automatic

alignment.

Description

The TDA7705 highly integrated tuner (HIT) is a

new generation of high performance tuners for

carradio applications.
