LMX2595EVM: How to phase lock three LMX2595 evaluation boards in order to get three coherent signals

Charles,

To do this, the first step apply a common reference to all three devices.

Then put all three devices SYNC mode so that the delay through the boards are all deterministic.

The next step is to send a SYNC pulse. If it is category 2 (Fout%Fosc=0), then you can do this in software. Otherwise, if it is category 3, (Fout%Fosc>0), then you need to send a timed pulse to the SYNC pin. The datasheet give more on this. See section 7.3.10.

Also, once this is done, remember that determinisitc phase is does not mean equal phase or zero phase. To adjust the phase of the individual devices, you can use the MASH_SEED word.
