您好。上面的曲线表示输入信号。DCO是数据输出的时钟，可以在上升沿读取数据。如手册描述
“ The AD9233 provides a data clock output (DCO) intended for capturing the data in an external register. The data outputs are valid on the rising edge of DCO, unless the DCO clock polarity has been changed via the SPI.”
时钟的输入不建议使用DSP产生，时钟的抖动会影响信噪比。请参考应用笔记AN-756，
