Hi, I have to generate a phase simulation signal having different phase on 9 DDS channels.
I arranged the circuit to synchronize each DDS same as datasheet. And conformed SYNC_IN signal that entered to each DDS. Also I did the DAC Calibration.
But DDS IF output didn't remain diiference of phase setting between DDS whenever power on/off.
Do you have any knowhow to synchronize each DDS.
