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.
