Intel Desktop Board YA810E Technical Product Specification

1.11 LAN Subsystem

The Intel 82559 Fast Ethernet Wired for Management (WfM) PCI LAN subsystem provides both
10Base-T and 100Base-TX connectivity. Features include:
•
32-bit, 33 MHz direct bus mastering on the PCI bus
•
10Base-T and 100Base-TX capability using a single RJ-45 connector with connection and
activity status LEDs
•
IEEE 802.3u Auto-Negotiation for the fastest available connection
•
Jumperless configuration; the LAN subsystem is completely software-configurable

1.11.1 Intel 82559 PCI LAN Controller
The Intel 82559 PCI LAN controller's features include:
•
CSMA/CD Protocol Engine
•
PCI bus interface
•
DMA engine for movement of commands, status, and network data across the PCI bus
•
Integrated physical layer interface, including:
 Complete functionality necessary for the 10Base-T and 100Base-TX network interfaces;
when in 10 Mbit/sec mode, the interface drives the cable directly
 A complete set of Media Independent Interface (MII) management registers for control
and status reporting
 802.3u Auto-Negotiation for automatically establishing the best operating mode when
connected to other 10Base-T or 100Base-TX devices, whether half- or full-duplex capable
 Integrated power management features, including support for Wake on LAN
