TDA7706中文资料HIT2高度集成AM/FM调谐器，具有HD接口数据手册ST规格书

描述 Description

The TDA7706 highly integrated tuner is a high/performance AM/FM tuner IC for car-radio applications, suitable for HD Radio™ reception.

It contains mixers and IF amplifiers for AM, FM and WX, fully integrated VCO and PLL synthesizer, IF- processing including adaptive bandwidth control, stereo-decoder, RDS decoder, and digital interfaces for external HD Radio™ decoding on a single IC.

AM/FM IBOC or DRM base band filtering is available in parallel to standard analog reception.

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 customization possibility through software control, automatic alignment and a powerful DSP for custom processing.
