R Pinout Guidelines Appendix A Xilinx recommends the following guidelines to improve design timing using the Virtex®-5 Tri-Mode Ethernet MAC: If available, use dedicated global clock pins for the Ethernet MAC input clocks. Use the column of IOBs located closest to the Ethernet MAC block. Use the RocketIO serial transceivers located closest to the Ethernet MAC block.
