TDA7786中文资料AM/FM汽车无线电的ELITE汽车级调谐器数据手册ST规格书

描述 Description

The TDA7786x (ELITE) tuner is an optimized high-performance AM/FM tuner IC family for car-radio applications, suitable also (in combination with an external baseband decoder) for HD Radio™ reception.

Its members integrate 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 base band filtering is available in parallel to standard analog reception.

The utilization of digital signal processing results in numerous advantages: 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.

Two versions of the device cover different application/performance requirements:

TDA7786: entry-level, high-performance tuner;TDA7786M: tuner with enhanced behavior in case of FM multipath, thanks to the proprietary MuSICA algorithm.

Both versions are HW- and SW-compatible.
