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. Architected for Small-Footprint, Low-Power Designs interrupts simultaneously, combined with intelligent filtering, The Intel 82574L/IT Gigabit Ethernet Controllers are ideal for cores, enables load-balancing the network traffic flows to GbE implementations on small form-factor Embedded designs improve throughput in multi-core platforms.
