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.
