DP83901数据手册集成电路（IC）的控制器规格书PDF

描述 Description

General Description
The DP83901A Serial Network Interface Controller (SNIC) is a microCMOS VLSI device designed for easy implementation of CSMA/CD local area networks. These include Ether net (10BASE5), Thin Ethernet (10BASE2) and Twisted-pair Ethernet (10BASE-T). The overall SNIC solution provides the Media Access Control (MAC) and Encode-Decode (ENDEC) functions in accordance with the IEEE 802.3 standard.
