摘要
针对美国AD(模拟器件)公司生产的DDS产品—AD9851芯片的功能特点,阐述了AT 89S52控制AD9851组成直接数字式频率合成信号发生器的应用设计电路,并对信号源的功能进行了C语言程序设计,完成了软件设计与实现.该程控信号源工作可靠,满足了高稳定度、高精度、高分辨率的要求,输出频率达20 MHz.
According to the characteristic and function of the chip AD9851 produced by AD company in USA, the application circuit of direct digital frequency supply oscillator in which the chip AD9851 is controlled by AT89S52 is designed. The design and realization of the software is achieved by the C programming language for the function of supply oscillator. The program-controlled supply oscillator works reliably, and has high stability, high precision and high resolution. The output frequency of supply oscillator can reach 20 MHz.
