5 / 77 page  DM9102H Single Chip Fast Ethernet NIC Controller Final 2 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. 2.
