I would like to sync 2 AD9833 together and just change the phase of one of them relative to the other in 1 Deg increments.
I see it is possible to use multiple AD9833 on one Arduino, but not sure if they are able to sync together like described for the AD9850/1.
Would I be able to use the onboard Nano 16Mhz clock for both AD9833 or is it better to use an external 25Mhz clock for both?
I don't know if the specks of Arduino Nano but a clock distribution system is required when you want to fan out the clock on to many devices. If you can buffer this clock with sufficient current and without affecting it's rise time and fall time performance then I think it is feasible.
Thank you very much for your reply.
I'm going to try that, as well as using an AD9834 instead because of the reset pin.
