ZC706 GT Serial TxRx

Jump to solution

Using ZC706 eval bd GT transceivers on Banks 109 and 110 (an Aurura IP core design) to FMC HPC conn with mezz bd with SMA conns.  I have assigned/used only one lane per bank, so there are 3 unused transceivers per bank.  I need to use those unused transceivers on those banks (109, 110) as direct hi-speed diff i/o to/from the PL.  Can this be done and how? any examples?

Thanks for the answer.  About the answer - That's too bad, because that means a whole separate bd will have to be added to buffer clocks and translate voltage levels for inputs to the GTX Ref clock inputs, whereas that function might have been provided by the unused GTX IOs.  Furthermore, the GTX 1.2v IO does not appear to be an industry standard and such buffers are hard to find.

I'm afraid these are dedicated pins and cannot be used as general purpose IO.
