The 3x3G is a mezzanine board that pairs with an EDT main board (for PCI or PCI Express) for high-speed data transfer. It has three channels, each having one 3Gb Xilinx RocketIO transceiver and one SFP for either an electrical RJ45 1GbE (1000 Base-T) Ethernet adapter or an optical LC.
The 3x3G has four additional RocketIO transceivers that connect to an internal 40-pin connector. Two quad-frequency oscillators allow eight different clock speecs.
