摘要
介绍了基于可编程DDS芯片AD9850设计的高精度频率相位发生器.通过计算机串口发送频率相位更新字,经过MAX232电平转换,再由单片机对数据格式进行转换后送入AD9850,从而产生所需的信号.
The signal generator of high precision frequency and phase based on programmable DDS AD9850 is described.The control data from the PC′s serial port is sent to an AT89C2051 through a MAX232 used as electric level conversion.The processor transforms these data format and sends them to an AD9850 for generating a signal needed.
