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
