How to Provide RefCLK for AD's DDS chip evaluation boards

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?


Thank you,
