Description
The TDA7706 highly integrated tuner is a
high/performance AM/FM tuner IC for car-radio
applications, suitable for HD Radio™ reception.
'!0'03
LQFP64
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.
