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 The Intel 82574L/IT Gigabit Ethernet Controllers are ideal for GbE implementations on small form-factor Embedded designs as well as Client and Server LAN on Motherboard (LOM) config- urations. This very small 9mm x 9mm, 64-pin, QFN (Quad Flatpack No-lead) silicon package provides a 40% reduction in total footprint over the previous generation. The Intel 82574L/IT Gigabit Ethernet Controllers consume less than 710mW in GbE mode and less than 300mW in 10/100 mode. The robust design also incorporates optional internal voltage regulation which can reduce the number of voltage supplies required from the platform to power core and I/O functions. Support of D0 and D3 power states is provided as well as Smart power-down at S0 no link and Sx no link. Support of PCIe power management wake up and Advanced power management (APM) wake up using special packets is provided as well as LAN disable function. Filled with Performance Optimization Capabilities The Intel 82574L/IT Gigabit Ethernet Controllers contain two transmit and two receive queues for the single port. The controller efficiently manages packets with minimum latency by combining parallel and pipelined logic architectures optimized for these independent transmit and receive queues. These queues, combined with Receive Side Scaling (RSS) and Message Signal Interrupt Extension (MSI-X) support, provide a toolset for optimizing the performance on multi-core CPU designs. Advanced interrupt-handling features to manage multiple interrupts simultaneously, combined with intelligent filtering, ordering and directing of packets to specific queues and cores, enables load-balancing the network traffic Read the full Product Brief Intel® 82574L and 82574IT Gigabit Ethernet Controllers Network Connectivity.
