The XPort3301 is a conduction- or air-cooled dual 10GBASE-T 10 Gigabit Ethernet XMC with front panel or rear I/O support. A x8 PCI Express 2.0 port is routed per VITA 42.3 to the P15 connector for interfacing with the host module.Front panel I/O for the 10GBASE-T 10 Gigabit Ethernet interfaces is provided with up to two RJ-45 connectors. The XPort3301 supports rear 10GBASE-T I/O through the P16 connector and utilizes X12d I/O mapping per VITA 46.9. The module utilizes automatic negotiation down to 100BASE-TX and 1000BASE-T on both 10GBASE-T ports. The XPort3301 can also support IEEE 1588 and the use of an externally sourced clock reference, such as a 1PPS, for synchronization.
