KU82596CA25

INTRODUCTION

The 82596CA is an intelligent, high-performance 32-bit Local Area Network coprocessor. The 82596CA implements the CSMA/CD access method and can be configured to support all existing IEEE 802.3 standards -TYPEs 10BASE-T, 10BASE5, 10BASE2, 1BASE5, and 10BROAD36. It can also be used to implement the proposed standard TYPE 10BASE-F.
