Description: 直接数字频率合成(DDS)是频率合成领域中的一项新技术 ,利用集成 DDS芯片能够满足高性能信号源的设计
要求。简要介绍了 DDS集成芯片 AD9951 的基本原理及功能特性。提出了一种以 AD9951 为核心 ,利用单片机控制技术的
通用信号源设计方法。给出了系统主要硬件电路的实现 ,并利用汇编语言开发了主控软件。实验结果表明 ,硬件电路结构
简单 ,软件控制灵活 ,软件和硬件拓展性好 ,输出信号频率稳定 ,分辨率高。-Direct Digital Frequency Synthesis (DDS) is a new technology in the field of f requency synthesis. Making use of
the integrated DDS chip can satisfy the requirement s of designing a high performance signal generator . In this article ,the prin2
ciple and function features of Direct Digital Synthesizer AD9951 is int roduced and a method to design a general signal generator
centered on AD9951 ,using a single chip to cont rol is proposed. The significant part of hardware circuit of the system is illus2
t rated and the main sof tware is developed in compiling programming language to cont rol the chip AD9951. Experiment result s
indicate that the hardware circuit const ruction is plain and the programming is flexible ,besides ,the hardware and sof tware are
both easily extended. Furthermore ,the output signal is stable and has high f requency resolution.
