Product Summary

The TDA7513 is a single-chip fm/am tuner. The TDA7513 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 TDA7513 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 and treble), balance and fading control to drive four output channels.
