DESCRIPTION

The TDA7518 multichip module combines in a sin-

gle compact 144-pin package the full functionality

of a state-of-the-art car-radio AM/FM tuner (from

antenna input to processed audio output, plus EE-

PROM for setup storage) with a minimized number

of required external components.

The following three devices are included (please

refer to the relevant datasheet for specifications):

– TDA7511, AM/FM tuner with fully integrated

tuning PLL, FM demodulator and IF band-

width control

– TDA7412, digitally controlled stereodecoder

and audioprocessor featuring AM/FM noise

blanking, multipath and quality detectors;

bass, treble, loudness controls as well as dy-

namic level compression with 3 stereo and 3

mono fully mixable inputs and four indepen-

dent speaker outputs.

– M24C01, 128 x 8 bit EEPROM

All chips are I2C-bus controlled.
