82574L GbE PCI-E Network Controller
The Intel
®
82574L GbE PCI-E Network controller is a single, compact, low-power component
that offers a fully-integrated PCI-Express* x1 10/100/1000 GbE controller with Media Access
Control (MAC) and Physical Layer (PHY) port. The device is compliant with PCI Express* Base
Specification, Revision 2.0. The 82574L GbE PCI-E Network controller enables a single-port
implementation in a relatively small area, so it can be used for server and client configurations
as a LAN-on-Motherboard (LOM) design. You can also use the 82574L GbE PCI-E Network
controller in embedded applications such as switch add-on cards and network appliances. The
82574L GbE PCI-E Network controller provides one PCI Express* lane operating at 2.5 GHz
with sufficient bandwidth to support a 100 Mb/s transfer rate. 32 KB of on-chip buffering
mitigates instantaneous receive bandwidth demands and eliminates transmit under-runs by
buffering the entire outgoing packet prior to transmission. The Intel
®
82574L GbE PCI-E
Network controller supports the following features:
Standard IEEE 802.3 Ethernet interface for 10BASE-T, 100BASE-TX, and 1000BASE-T
(802.3, 802.3u, and 802.3ab) applications
NC-SI or SMBus connection to a Manageability Controller (MC)
IEEE 1149.1 JTAG
Support for PCI 3.0 Vital Product Data (VPD)
IPMI MC pass-through; multi-drop NC-SI
TimeSync offload compliant with 802.1AS specification

82567 Gigabit Network Connection Physical Layer Transceiver
(PHY)
The Intel
®
82567 Gigabit Network Transceiver is a single-port Gigabit Network Layer
Transceiver (PHY) that connects to the Media Access Controller (MAC) through a dedicated
interconnect. The 82567 Gigabit Network Transceiver is based on Intel’s Gigabit Network PHY
technology, and supports operation at data rates of 10/100/1000 Mb/s. The Intel
®
82567 Gigabit
Network Transceiver works with ICH9/ICH10 that incorporates and integrates the MAC, which is
referred to as the ICH10 LAN. The Intel
®
82567 Gigabit Network Transceiver interfaces with the
MAC through two interfaces:
Gigabit LAN Connect Interface (GLCI): A high-speed serial interface based on 802.3
serializer deserializer
LAND Connect Interface (LCI): A low-speed proprietary parallel bus.
The 82567 Gigabit Network Transceiver operates using both interfaces—the GLCI for 1000Mb/s
traffic and the LC for all other traffic types.
