Introduction

The STA680M is an HD-radio base-band processor for car-radio applications. The STA680M functionality includes audio decompression and data processing, while multiple interfaces ensure flexible integration into the system. The STA680M 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 or, alternatively, it features FM Maximum Ratio Combining Diversity for superior reception performance. STA680M supports FM/AM analog/digital AAA algorithm by mean of specific FW.
