The TDA7514 is a device for car-radio applications that combines full RF front-end functions with advanced audio-processing capabilities. As far as FM and AM functions are concerned, the TDA7514 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, AM and FM noise blanking (AM noise blanking comprises one IF NB as well as an audio NB). The FM stereo decoder and the noise blanking functions are realised entirely without external components. The FM front-end circuit features an image-rejection mixer that allows the simplification of the external preselection filter, and a very low noise level that allows getting rid of the external preamplifier with no loss in sensitivity.
