Product Summary

The DM9102DEP is a fully integrated and cost effective single chip Fast Ethernet NIC controller. It is designed with low power and high performance process. The DM9102DEP is a 2.5/3.3V device with 5V tolerance. The DM9102DEP provides direct interface to the PCI bus and supports bus master mode to achieve the high performance of the PCI bus. In the media side, the DM9102DEP 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 DM9102DEP to take the maximum advantage of its abilities.
