I am looking to use an AD product to create several synchronized sinusoidal signals with excellent phase resolution. I would like to purchase evaluation boards for one of the following products AD9854, AD9959, AD9914 but have not decided which one yet. For all of these, I will need to provide a reference clock. Can someone tell me how to do this?
I was looking at the AD9573. Would this be appropriate? Will I need to design a PCB? Or, is there some ready-made clock source I can buy for relatively cheap?
