TDA7705中文资料高度集成的调谐器数据手册ST规格书

描述 Description

The TDA7705 highly integrated tuner (HIT) is a new generation of high performance 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, stereo decoder and RDS 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 and automatic alignment.
