WARP FPGA Board MGTs

The Virtex-4 FPGA is equipped with 10 pairs of differential multi-gigabit transceivers. The MGTs can support data rates of up to 6.5 Gbps including standards such as SATA, gigabit Ethernet and Infiniband. Each of these requires a different clock speed for best performance. On the FPGA Board three different connectors have been provided: SATA host and target, HSSDC2 jacks and SFP modules.

The MGTs on the FPGA are organized in two columns. Each MGT in a column can share clock sources.
