I am trying to work with two of AD9857 DDSs in a synchronised way.
In order to do that,
at the same time, REFCLK, DATA etc ,
I configure these DDSs performing an automatic synchronisation.
The problem I find is that, after powering up them , I see that the phase of that signal has not synchronized.
How can I maintain the phase relation of the two outputs , when I will be powering up the two of AD9857 DDSs?
Thank you in advance.
