I see the Q&A "ad9279-65ebz can't operate at 80MHz. Why?".
The AD9279 DUT part@80MHz is the same 65MHz.
Would you send me the AD9279-65EBZ Evalboard circuit schematic?
Thank you for your interest in AD9279. The main engineer supporting AD9279 is traveling at the moment. I'm attaching the AD9279 evaluation board schematic I have.
I hope this gives you what you need until he returns.
