Can the GTY Ultrascale+ transceiver RX Termination be disabled?

i.e. remove it completely. Why? trying to implement a ping-pong transceiver. Port RXTERMINATION is to be set via the wixard. I was wondering what it really did?

Re: Can the GTY Ultrascale+ transceiver RX Termination be disabled?

The RX termination can be set to either float, programmable, or to MGTAVTT. This is set by RX_CM_SEL[1:0]. See UG578 page 186. The use modes are described in page 187-189.
Would float be applicable for your use case?

RXTERMINATION is a reserved port and should not be changed.
