(PCIe) x1 Connectivity
The Intel® 82574L/IT Gigabit Ethernet Controllers provide a
pathway from legacy PCI/PCIx designs to higher performing
PCIe-based designs. These single-port Controllers use a PCIe one
lane (x1) interface operating at 2.5 GHz. The Intel 82574L/IT Gigabit
Ethernet Controllers provide fully integrated Gigabit Ethernet Media
Access Control (MAC) and Physical-Layer (PHY) capabilities that
can be configured for either 1000 Mb/s or 10/100 Mb/s modes of
operation. Some optional PCIe extensions are also supported in
the Controllers to enhance platform capabilities for specific usage
modes. Each Controller provides MDI (Copper) standard IEEE 802.3
Ethernet interface for 1000BASE-T, 100BASE-TX, and 10BASE-T
applications (802.3, 802.3u, and 802.3ab). The Intel 82574L/IT also
enables a quick migration from custom interconnects to Ethernet.
