DP83901A SNIC

Serial Network Interface Controller

General Description

The DP83901A Serial Network Interface Controller (SNIC) is

a microCMOS VLSI device designed for easy implementa-

tion of CSMACD 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 8023 stan-

dard

The integrated ENDEC module allows Manchester encod-

ing and decoding via a differential transceiver and phase

lock loop at 10 Mbitsec Also included is a collision detect

translator and diagnostic loopback capability
