摘　　要：AD9858是一款高性能DDS芯片,它集成了10位高速D/A转换器,能够输出频率高达450MHz的正弦波信号。本文详细介绍了AD9858的工作流程及时序关系、寄存器的配置方法,以及基于AD9858的调频信号源硬件设计实现。The AD9858 is a high performance DDS chip with the integration of 10-bit D/A converter at high speed, from which the sine wave signal with the frequency of up to 450MHz is output. The paper introduces the work flow and time sequence relationship of the AD9858, as well as how to configure registers in the AD9858 and how to design and implement the hardware for the AD9858-based frequency-modulated signal source.
