I am designing device, based on Virtex-4 FX20 chip. This device is going to produce lots of data and I would like to send it to processing computer using Gigabit Ethernet interface. I am lucky to have two Ethernet MAC's built-in in the FPGA. Also we would like to use RocketIO transceivers to connect our Ethernet MAC's to physical media. Here is my problem begins. I need to connect magnetic to RocketIO differential outputs. I have searched Xilinx web-site, but found nothing about this issue. There are two user guides, one about Tri-mode Ethernet MAC and another about RocketIO MGT. Both guides full of useful information, but none of them highlights this issue. They just cross-reference each other on this matter :)
So, does any one has any experience in putting Ethernet MAC (hardware or IP Core) and RocketIO transceiver to work together in Gigabit Ethernet configuration (without using external PHY)? Xilinx web-site has an Answer Record 13928, stating full compliance Virtex-2 Pro RocketIO MGT to all Gigabit Ethernet standards, so I assume Virtex-4 MGT is compliant to all Gigabit Ethernet standards as well.
