Hi,
Yes, there is no footnote about the refclk but they can be driven when unpowered as long as there is proper coupling and the voltages are in the specified limits.

Regular ContributorHi,
May I ask which transceiver tile are you using?
Regards
New ContributorIt's the F tile.
Regular ContributorHi,
Specifically for the PCIe application, the F-tile supports the Hot Plug feature. Refer to the following documentation:
I think this is what you were looking for.

New ContributorThanks Ash.
Below image is what I see for Hot Plug capability, indicating that device can be added or removed from system during runtime.
It's not clear to me entirely from this that the Transceiver Pins themselves can handle AC voltages (assuming CLK/Data lanes are AC coupled) while the F tile is unpowered/unconfigured or if this assumes the board hardware implements power gating, for example with a buffer on the F tile's PCIe clock input that only propagates the clock to the F tile once the F tile's power rails are present.
