A way to synchronize multiple AD9857

Hello,

I am trying to work with two of AD9857 DDSs in a synchronized way.

In order to do that, at the same time, REFCLK, DATA, etc,

The problem I find is that latency of output will differ 1 PDCLK  as Figure 33 and Figure 34 in the datasheet,

Is there any good way to synchronize output with PDCLK?

Thanks,

Yong
