Product Details

The Intel® Ethernet Connection X557 family is a 10 Gigabit Ethernet (GbE) copper networking Physical Layer (PHY) for workstation, server, and embedded designs that have critical space and power constraints. The Intel® Ethernet Connection X557 family offers three design options: X557-AT (single 10 GbE PHY), the X557-AT2 (dual 10 GbE PHY), and the X557-AT4 (quad 10 GbE PHY)that provides connectivity for Network Interface Cards (NICs) and LAN on Motherboard (LOM) applications that require 10GBASE-T capability.
