HD-Radio base-band receiver

The STA680 is an HD-radio base-band processor for car-radio applications. The STA680 functionality includes audio decompression and data processing, while multiple interfaces ensure flexible integration into the system.

The STA680 takes full advantage of HD 1.5 Radio benefits including CD-like audio quality from HD Radio FM broadcasts and FM-like audio quality using HD Radio AM, while program associated data or traffic information is received from the second channel.
