Features: brand new and high quality This is a compact, low-power component that provides fully integrated Gigabit Ethernet media access control (for Mac) and physical layer (PHY) ports. The 82583L uses the PCI for Express x architecture and provides a single port for implementation in a relatively small area, so it can be used for server and client configuration LAN (LOM) designs on the main board. for Intel 82583L can also be used for embedded applications, such as switch add-on cards and network devices. It is very suitable for consumer electronics and other small-scale embedded applications. Low power consumption: <750 mW GbE and <300 mW 10/100. Operating system support: Linux, FreeBSD, for Windows home server.
