Intel® LXD972M Transceiver Demo Board (Board Rev A1)

1.0 Introduction

This document describes the typical hardware set-up procedures for the Intel® LXD972M Transce iver Demo Board (called hereafter the LXD972M Demo Board). The LXD972M Demo Board is a platform for evaluation of the Intel LXT972M Single-Port 10/100 Mbps PHY Transceiv er (c al le d he re af t er th e LX T 9 72 M Trans c ei ve r ) .

The LXD972M Demo Board allows syste m designers to test the following:

• 10 Mbps and 100 Mbps link perform ance

• Auto-negotiation

• Register func tionality

The LXD972M Demo Board requires only a single 3.3V power supply.
