DM9102A

www.DataSheet4U.com DM9102A Single Chip Fast Ethernet NIC controller General Description The DM9102A is a fully integrated and cost-effective single chip Fast Ethernet NIC controller. It is designed with the low power and high performance process. It is a 3.3V device with 5V tolerance then it supports 3.3V and 5V signaling. The DM9102A provides direct interface to the PCI or the CardBus. It supports bus master capability and fully complies with PCI 2.2. In media side, The DM9102A interfaces to the UTP3,4,5 in 10Base-T and UTP5 in 100Base-TX. It is fully compliance with the IEEE 802.3u Spec. Its auto-negotiation function will automatically configure the DM9102A to take the maximum advantage of its abilities. The DM9102A is also support IEEE 802.3x fullduplex flow control. The DM9102A supports two types of power-management mechanisms. The main mechanism is based upon the OnNow architecture, which is required for PC99. The alternative mechanism is based upon the remote Wake-OnLAN mechanism.
