Introduction

The EV71C64A Evaluation Board (EVB) is developed based on Microchip’s PD77728 PoE controller/manager.

EV71C64A demonstrates four IEEE? 802.3bt 4-pair ports using PD77728 in Unmanaged Auto mode.

The PD77728 device is a part of Microchip’s seventh generation IEEE 802.3bt compliant Power over Ethernet (PoE)

Power Sourcing Equipment (PSE) family. This device is a fully integrated eight port PoE controller and PoE manager

with integrated Field Effect Transistor (FET) switches and current sense resistors. The PD77728 chipset supports

IEEE 802.3af/at/bt standards and legacy/pre-standard PD detection. The device is available in a 56-pin 8 mm × 8 mm

QFN package.

EVB includes green and yellow bi-color LEDs that provide visual status of each port by two dedicated LEDs per port.

The evaluation system has the following features:

? RJ45 Gang (contains four RJ45 connectors)

? Four 4-Pair Ports Structured by PD77728

? Switch Domain USB Interface to be Connected to a PC with Microchip GUI

? PoE Controller Manual Reset and Serial Communication Setting

? Green and Yellow Bi-Color LED Status Indication for all Four Ports

? Requires a Single Power Source only

? 0 °C to 40 °C Operating Temperature

? RoHS Compliant
