Diff Trace impedance for Ultrascale+ Aurora 8Gbps Interface

Jump to solution

I haven't found this mentioned in the docs or forums, but I need to know what the nominal impedance of the differential routes should be on the board to support 8Gbps Serial transceivers using Aurora to communicate between two such FPGAs.

hi @bob_w,

please design your differential traces for 100Ohm impedance.
