Peripheral Component Interconnect Express (PCIe) is based on point-to-point topology, a PCIe bus supports full-duplex communication between points and the system is not limited to the slowest peripheral on the bus in the same way it is with PCI. The PCIe link between devices can use 1-32 lanes. A single lane (x1) PCIe Card can be used in a multi-lane slot (x4, x8, x12, x16 and x32), and it is automatically negotiated during device initialization to use the highest mutually supported lane count. A PCIe Card fits into a slot of its same size or larger but may not fit into a smaller slot. Some slots will permit longer cards but negotiate the best electrical connection.
Lantronix’ PCIe NICs support Fast Ethernet, Gigabit Ethernet and 10 Gigabit Ethernet networks. Our Power-over-Ethernet PCIe NIC also delivers power and data to connected devices such as VoIP phones.
