4-port Ethernet PCI Mezzanine Card

The PMC401 is 4-port Ethernet PCI Mezzanine Card (PMC) based controller for use in embedded applications, designed to withstand extreme environmental conditions.

A quad 10/100/1000Mbit Ethernet PMC based controller for use in embedded applications. The PMC401 contains four Intel 82574IT, low power single port Gigabit Ethernet controllers to support hardware-based time stamping, jumbo frames and host offloading features like IPv4 and IPv6 checksum. The Ethernet controllers are transparently connected to the PMC PCI interface via a PLX PCI to PCIe bridge and PCIe switch. The PMC PCI interface is converted into a one lane 2.5Gbs PCIe for each controller.

The front panel has four RJ45 copper connectors with LEDs for a combined link/activity indication. For each Ethernet controller there is a bootflash chip available in which a bootloader may be programmed (bootloader not included).

The PMC401 is available in standard temperature, 0°C to +60°C, and industrial temperature, -40°C to +85°C.

Driver support is also included for most commonly used operating systems.
