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. The AD9852’s circuit architecture allows the
