Hi. I have a quick question regarding the ADF4355-2. I own the official EVB by Analog that allows to provide the input reference though the SMA connector, thus with a nominal 50ohm single-ended input impedance.
I was wondering if there is the possibility of "bypassing" the SMA input and provide a high-impedence signal with 3.3Vpp amplitude directly to the ADF4355, in order to lock the PLL to this kind of reference.
If this is not feasible, how do you suggest me to proceed? I was thinking about a voltage divider, but it seems to me it's a too naive solution.
