PC82545RDE

Introduction

The Intel® 82545GM Gigabit Ethernet Controller is a single, compact component with an integrated Gigabit Ethernet Media Access Control (MAC) and physical layer (PHY) functions. The Intel® 82545GM enables Gigabit Ethernet implementations in a very small area and can be used for desktop and workstation PC network designs as well as backplane applications with critical space constraints.
