DESCRIPTION
The TDA7513T is the first device for car-radio ap-
plications that combines full RF front-end func-
tions with audio-processing capabilities.
As far as FM and AM functions are concerned , the
TDA7513T features front-end processing, includ-
ing the digital tuning PLL, IF processing with de-
modulation and variable-bandwidth IF filtering
(ISS), stop station and quality detection functions,
FM stereo decoding by means of a fully-integrat-
ed, adjustment-free dedicated PLL and, finally, FM
noise blanking. The FM stereo decoder and noise
blanker functions are realized entirely without ex-
ternal components.
The audio processor section comprises input se-

lectors for two quasi-differential external sources,
volume control, tone control (bass, mid and tre-
ble), balance and fading control to drive four out-
put 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
I
2
Cbus-driven and therefore under the control of
the car-radio maker. The I
2
C bus allows further-
more the user to realize the full electric alignment
of all the external coils, therefore removing the
need for hand-made or mechanical adjustments.
