DM9102H
Single Chip Fast Ethernet NIC Controller
1. General Description
The DM9102H is a fully integrated and cost effective single
chip Fast Ethernet NIC controller. It is designed with low
power and high performance process. It is a 1.8V/3.3V
device with 5V tolerance.
The DM9102H provides direct interface to the PCI bus and
supports bus master mode to achieve the high performance
of the PCI bus. It fully complies with PCI 2.2. In the media
side, the DM9102H interfaces to the UTP3, 4, 5 in 10Base-T
and the UTP5 in 100Base-TX. It is fully compliant with the
IEEE 802.3u Spec. Its auto-negotiation function will
automatically configure the DM9102H to take the maximum
advantage of its abilities. The DM9102H also supports IEEE
802.3x’s full-duplex flow control.
The DM9102H supports two types of power management
mechanisms. The main mechanism is based on the On
Now architecture, which is required for PC99. The
alternative mechanism is based upon the remote
Wake-On-LAN mechanism.
