描述 Description

General Description
The DM9008 Ethernet controller is a highly integrated design that provides all Medial Access Control (MAC) and Encode-Decode (ENDEC) functions in accordance with the IEEE 802.3 standard. Network interfaces include 10BASE5 or 10BASE2 Ethernet via the AUI port and 10BASE-T via the Twisted-pair. The DM9008 Ethernet controller can interface directly to the PC-AT ISA bus without any external device.
