Abstract

The main feature and internal structure of AD9958 - namely the high performance DDS chip is introduced and the control method of output single-tone mode by using AD9958 as direct frequency synthesizer is described. And the hardware functional block diagram of the double channels DDS source by using AD9858 and chip monolithic computer 89C51is provided. The result shows that AD9958 can be used to correct imbalances between signals and perform synchronization of multiple devices.
