10 gigabit Ethernet controllers

Intel® Ethernet Controller X540 Family

The Intel® Ethernet Controller X540 is Intel’s latest industry-leading innovation to reduce the cost of 10 Gb Ethernet and bring it to the broad server market. The small, 25 x 25 mm package with two low power 10GBASE-T ports is designed using industry-leading integrated RFI filters for 100 meter cable lengths. Designed for LAN-on-motherboard (LOM), network daughter cards, and converged network adapter (CNA) integration, the single-chip design provides significant bill of materials (BOM) savings by reducing the support components (bridge chips, crystals, and electrically erasable programmable read-only memory (EEPROM)) required when compared to other multichip solutions.
