Demo Board for 10/100 and 100BASE-FX Applications — LXD970A

1.0General Description

The LXD970A Demo Board is a versatile 10/100Mbps Ethernet media access unit (MAU) that demonstrates all of the integral features of the LXT970A Fast Ethernet Transceiver.

The LXD970A provides a working platform for evaluation of the LXT970A Fast Ethernet Transceiver in 10BASE-T and/or 100BASE-TX/FX applications.

The LXD970A Demo Board is configured with a single chip 10/100Mbps, IEEE 802.3u compliant, Fast Ethernet Transceiver unit (LXD970A). The demo board is designed to plug into a transceiver test box via a standard 40-pin MII connector. This allows system designers to test 10Mbps and 100Mbps link performance, auto-negotiation and register functionality prior to board prototyping.

The LXT970A also provides an ECL-type interface for 100BASE-FX link testing.

This document describes typical Demo Board setup procedures for a 100BASE-TX environment.

Before using the Demo Board, review the LXT970A Fast Ethernet Transceiver data sheet for device functionality and specifications.
