Adhere to these placement guidelines for the true differential I/Os.
  • Do not place LVSTL, SLVS-400, or DPHY I/O standard in the same I/O lane as the True Differential Signaling I/O standard.
  • You can place True Differential Signaling I/O standard in the same I/O lane as LVSTL I/O standard only if you use the True Differential Signaling input as a reference clock.
  • If you use the SLVS-400, DPHY, or 1.05 V, 1.1 V, or 1.2 V True Differential Signaling I/O standard, you can place only the LVCMOS I/O standard in the same I/O lane.
