Product Details

The Intel® 82576 GbE Controller is a single, compact, low power component that offers two fully integrated Gigabit Ethernet Media Access Control (MAC) and physical layer (PHY) ports.

It uses the PCIe* v2.0 (2.5GT/s). It enables two-port implementation in a relatively small area and can be used for server system configurations such as rack mounted or pedestal servers, where it can be used as add-on NIC or LAN on Motherboard (LOM) design.

Another system configuration is blade servers, where it can be used as LOM. The 82576 can also be used in embedded applications such as switch add-on cards and network appliances.

The 82576NS supports 2 ports with either an internal PHY or a SerDes or SGMII port which may connect to an external PHY or directly to a blade connection for MAC to MAC communication.
