Single Chip PCI Fast Ethernet NIC Controller DM9102H


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 1.8/3.3V device with 5V tolerance.
It 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. It is pin and software compatible to DM9102D. 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.
The auto-negotiation and HP Auto-MDIX function can automatically configure the DM9102H to take the maximum advantage of its abilities. The DM9102H 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.
Two different current saving mechanisms are integrated: The main mode is based on the OnNow Achitecture that is required for PC99. Alternative Modes is based on Remote Wake-on-LAN.
