STMicroelectronics TDA7514
The TDA7514 is a device for car-radio applications that combines full RF front-end functions with advanced audio-processing capabilities. 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.| Part No. | TDA7514 |

DESCRIPTION
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). A 6 bit on- board ADC makes a digitised version of the Smeter available to the µP via I2Cbus. The audio processor section comprises input selectors for one stereo single-ended source, one stereo quasi-differential source and a mono differential source.
