I am trying to work with two of these DDSs in a synchronised way. In order to do that, I connect the synclk output of the first of these to the syncin of the second one. I configure the second one of these DDSs (slave) performing an automatic synchronisation.
The problem I find is that, when I power down the DAC output, when powering it on again I see that the phase of that signal has changed.
How can I maintain the phase relation of the two outputs when I will be switching on and off the DDSs?
Thank you in advance
