Introduction

The TDA7703 highly integrated tuner (HIT44) is part of a family of tuners for carradio applications. It contains mixers and IF amplifiers for AM and FM, fully integrated VCO and PLL synthesizer, IF-processing including adaptive bandwidth control (FM), stereo decoder on a single chip. The utilization of digital signal processing results in numerous advantages against today's tuners: Very low number of external components. Very small space occupation and easy application. Very high selectivity due to digital filters. High flexibility by software control. Automatic image rejection alignment.
