DM9102DEP Product Brief
Single Chip Fast Ethernet NIC Controller
May. 2008 Rev.1.0
The DM9102D 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 2.5/3.3V device with 5V
tolerance.
The DM9102D 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 DM9102D 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. The auto-negotiation and
HP Auto-MDIX function can automatically configure the DM9102D to take the maximum
advantage of its abilities. The DM9102D also supports IEEE 802.3x’s full-duplex flow
control to prevent the receive overflow of link partner. The IPv4 IP/TCP/UDP checksum
generation and checking can reduce the system CPU utilization.
The DM9102D supports two types of power management mechanisms. The main mechanism
is based on the OnNow architecture, which is required for PC99. The alternative mechanism
is based upon the remote Wake-On-LAN mechanism.
