This is regarding PCB layout design. I did take a look at the revA of UG-992 where it has mention about PCB(RF, digital) layout guidelines. However, We are seeing some fast transient signal coupling into RF path. Please see picture attached.

 

Question: could there be layout issue that ref spurs or fast JESD type of signal can couple into RF path?
