Abstract：Direct digital frequency synthesis( DDS )is an advanced frequency synthesis technology,which has the feature as fast frequency switching speed,high frequency resolution,agile control,etc. And it is widely used in radar and communicaition fields. In this paper,a design scheme of dual-DDS broad band frequency-hopping synchronization system based on AD9915 is in?troduced. Microcontroller Unit is used to realize the configuration of dual-DDS. The key points for realizing synchronization of key control signals are expounded according to the main characteristics and internal structure of AD9915,and the hardware interface is given as well as the controlling flow of system software to ensure stable synchronization of frequency and phase. Experiments and tests indicate the feasibility of the dual-DDS broad band synchronization system.
