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 Ethernet (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.

The integrated ENDEC module allows Manchester encoding and decoding via a differential transceiver and phase lock loop at 10 Mbit/sec. Also included is a collision detect translator and diagnostic loopback capability.
