VSC8502 Evaluation Board

2 Introduction

The VSC8502 device is a low-power, cost-optimized, dual-port gigabit Ethernet PHY. It features
integrated, line-side termination to conserve board space, lower EMI, and improved system
performance. To further reduce system complexity, component count, and system cost, the VSC8502
device can operate from a single 3.3 V supply using integrated voltage regulators. Additionally,
integrated RGMII timing compensation eliminates the need for on-board delay lines. The device also
optimizes power consumption in all link operating speeds and features Wake-on-LAN (WOL) power
management using magic packets.

This document describes the architecture and usage of the VSC8502 Evaluation Board (VSC8502EV). The
Quick Start section describes how to install and run the graphical user interface (GUI) to fully control the
evaluation board.
