Description
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
