Chapter 5: Board Design Guidelines
• Eliminate routing of GTX transceiver signals and SelectIO interface signals on
adjacent layers. Be aware of the potential of broadside coupling if these signals are
routed on adjacent layers.
• Maintain isolation of the return current paths for both the SelectIO interface signals
and the GTX transceiver signals including both traces and vias.
• The power islands for the GTX transceivers are also a potential source for SelectIO
interface induced noise. SelectO interface signals should not be routed over the GTX
power islands.
