Design of a wideband frequency synthesis based on DDS
Yang Zheng · Electronic Design Engineering · 2011
Aiming at a high performance DDS chip AD9858,a wideband frequency synthesis is introduced in this paper.The working principle of DDS is analyzed The principle block diagram and implementation process of this wideband frequency synthesis are given and software control flow is introduced.The phase noise and spurious performance of this system is also analyzed shortly.The test result shows that the wideband frequency synthesis has good phase noise and superior performance and reaches the desire design requirement.
