I want to use an external crystal in order to clock the AD9959/PCBZ DDS. I have read that the crystal frequency has to be between 20 - 30 MHz. However, I haven't found other restrictions or specifications that the crystal should to accomplish.  


I will appreciate very much if someone could tell me which other considerations I have to take into account in order to buy an external crystal for the AD9959/PCBZ DDS. I would like to know if there is some specific crystal or which is recommended for this board. 


Thank you very much.
