摘要
针对DDS器件AD9852的功能特点,设计了通过AVR单片机ATmega128控制AD9852芯片实现的程控信号源电路,并对ATmega128与AD9852之间的硬件接口电路以及软件功能的实现进行了介绍.通过此设计可以方便地实现对信号源输出频率、相位和AD9852各种模式的控制,使之能输出高稳定度、高分辨率和多模式的信号.
AD9852＇s functions and features are described,and the design circuit of signal generator controlled by ATmega128 and AD9852 is introduced as well as the circuit realization of software and hardware between ATmega128 and AD9852.From the perspective of the real working effects of the circuit design,the output wave is satisfied with the demand of high stability,high precision and multi-mold signal.
