TDA7513T

Single chip FM/AM tuner

with stereo decoder and audio processor

Features

■ AM/FM tuner for car radio

■ Integrated tuning PLL

■ Variable bandwith FM IF filter (ISS)

■ Fully integrated FM stereo decoder

■ fully integrated FM noise blanker

■ Highly integrated audio processor

Description

The TDA7513T is the first device for car-radio

applications that combines full RF front end

functions with audio-processing capabilities.

As far as FM and AM functions are concerned ,

the TDA7513T features front end processing,

including the digital tuning PLL, IF processing

with demodulation and variable bandwidth IF

filtering (ISS), stop station and quality detection

functions, FM stereo decoding by means of a fully

integrated, adjustment free, dedicated PLL and,

finally, FM noise blanking. The FM stereo decoder

and noise blanker functions are realized entirely

without external components.

The audio processor section comprises input

selectors for two quasi-differential external

sources, volume control, tone control (bass, mid

LQFP80

and treble), balance and fading control to drive

four output channels. A soft mute function and an

RDS mute function are included to handle source

change as well as RDS AF search without abrupt

changes in the audio level.

Most of the parameters in the front-end section

are I2C bus-driven and therefore under the control

of the car radio maker. The I2C bus allows

furthermore the user to realize the full electric

alignment of all the external coils, therefore

removing the need for hand-made or mechanical

adjustments.
