Single-chip FM/AM Tuner With Stereo Decoder And Audio Processor

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. By STMicroelectronics
