GENERAL DESCRIPTION
The AD9852 digital synthesizer is a highly integrated device that uses advanced DDS technology, coupled with an internal high-speed, high-performance D/A converters and a comparator to form a digitally-programmable agile synthesizer function. When referenced to an accurate clock source, the AD9852 generates a highly stable, frequency-phase amplitude-programmable sine wave output that can be used as an agile L.O. in communications, radar, and many other applications. The AD9852’s innovative high-speed DDS core provides 48-bit frequency resolution (1 microHertz tuning steps). Phase truncation to 17 bits assures excellent SFDR.
