We recently purchased an AD9914 eval board to help generate microwave frequencies for our application. We have been trying to understand how to do profile changes in a triggered way. We would like to change between the 8 programmable profiles of the board. We have an external timing system that would send a trigger signal to an external register to change the profile pins. However, we are running into problems synchronizing the profile change edge with the SYNC_CLK of the board. Is there a way to set up the AD9914 such that the profile will change on the next SYNC_CLK edge? If not, do you have any suggestions on a simple way to create an synchronized (with SYNC_CLK) write signal from an unsynchronized one? In terms of timing jitter we are not too concerned with jitter on the order of a few clock cycles.
Thank you for your help.
