User Guide PD-IM-7618T4H and PD-IM-7618T4 Eight Port PoE Evaluation Boards Doc Version 1.0 Document Number PD-000395299 PD-IM-7618T4H and PD-IM-7618T4 User Guide 1. Product Overview The PD-IM-7618T4H and PD-IM-7618T4 evaluation boards are developed based on Microchips PD69208T4and PD69210 chipset: The PD-IM-7618T4H demonstrates the operation of eight 4-pair ports (2 pairsets) according to IEEE802.3bt. The PD-IM-7618T4 demonstrates the operation of eight 2-pair ports (a single pairset). Microchips PD69208M/PD69208T4/PD69204T4 Power over Ethernet (PoE) manager IC integrates power, analog, and state-of-the-art logic into a single 56-pin, plastic QFN package. The device is used in Ethernet switches and midspans/injectors to allow network devices to share power and data over the same Ethernet cable. The PD69208M/PD69208T4 device is an 8-port and PD69204T4 device is a 4-port, mixed-signal and high voltage PoE driver. Together with the PD69210 external MCU, it performs as a PSE system. Microchips PD69210 PoE controller is a cost-effective and pre-programmed MCU designed to implement enhanced Mode PoE system. The PD69208M/PD69208T4/PD69204T4 and PD69210 chipset supports PoE powered device (PD) detection, power-up, and protection according to IEEE802.3af/at/bt standards as well as legacy/pre-standard PD detection. It provides real- time PD protection through the following mechanisms: overload, under-load, over-voltage, over-temperature, and short-circuit, and enables operation in a standalone mode. It also executes all real-time functions as specified in IEEE802.3at and IEEE802.3bt standards, including PD detection (AF and AT). The PD69208M/PD69208T4/PD69204T4 support supply voltages between 32 V and 57 V without additional power sources. A system that powers over 4 pairs is implemented by combining 2 ports of PD69208M/T4 and PD69204T4, enabling an extra feature for simple and low-cost high-power PD devices. Ongoing monitoring of system parameters for the host software is available through communication. For higher reliability, internal thermal protection is implemented in the chip. The PD69208M/PD69208T4/PD69204T4 is the most integrated PSE IC including internal MOSFET and sense resistor to achieve a low power dissipation. The PD69210 features an eSPI bus for each PD69208M/PD69208T4/PD69204T4. It is based on the Microchip D21 2 family. The PD69210 utilizes an I C or UART interface to the host CPU. It is designed to support software field- upgradable through the communication interface. The evaluation system provides designers with the required environment to evaluate the performance. The evaluation system has the following features. Two RJ45 gangs (each contains 4 RJ45 connectors) Switch domain isolated from PoE domain Switch domain USB interface to be connected to a PC with Microchip GUI PoE controller manual reset & serial communication setting LED status indication for all ports (LED stream) Requires single power source only 0 C to 40 C working temperature RoHS compliant Microsemi Proprietary and Confidential 2
