Product Overview
The PD-IM-7604+4M/T4H evaluation board is developed based on two PD69208M/PD69208T4 +
PD69204T4 and PD69200 chipsets, and demonstrates the operation of four 4-pair ports and four 2-pair
ports systems.
Microsemi's 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 to allow network devices to share power and data over the same 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 PD69200 external MCU, it perform as a PSE system. Microsemi's
PD69200 PoE controller is a cost-effective and pre-programmed MCU designed to implement enhanced
mode.
The PD69208M/PD69208T4/PD69204T4 and PD69200 chipset supports PoE powered device (PD)
detection, power-up, and protection according to IEEE 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 draft 3.0 standards,
including PD detection (AF and AT).
PD69208M/PD69208T4/PD69204T4 supports supply voltages between 32 V and 57 V without additional
power sources. A system that powers over 4 pairs can be 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. Internal thermal protection is implemented in the chip. The PD69208M/PD69208T4
/PD69204T4 is a low power dissipation device that uses internal MOSFETs and internal 100 m
Ω
sense
resistors.
The PD69200 features an ESPI bus for each PD69208M/PD69208T4/PD69204T4. It is based on
Freescale's Kinetis_L family MKL15Z128VFM4 embedded with an ARM Cortex™-M0+ core. The PD69200
utilizes an I
2
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
and implementation of the following:
PD69204T4 (four ports) and PD69208T4 (eight ports) PoE managers and PD69200 PoE controller (in
board PD-IM-7604+4T4H)
PD69208M (eight ports) PoE manager and PD69200 PoE controller (in board PD-IM-7604+4MH)
The evaluation board, shown in the following illustration, enables PoE designers to evaluate Microsemi's
PoE solution with flexibility and easy configuration. The application circuit of two PD69208M
/PD69208T4 + PD69204T4 and PD69200 chipset is compact in size (highlighted in the white box on
board).

Input supply to the board is DC and it can be fed through the V
IN
connector (see
electrical characteristics
(see page 7)
for the input voltage range). The auxiliary power supply (5 V and 3.3 V) for the PD69208M
/PD69208T4/PD69204T4 is generated internally and the auxiliary power supply (3.3 V) for the PD69200
MCU is generated using a 3.3 V isolated DC
–
DC converter.
The board communicates with the host environment using UART communication, available through a
USB connector (U11). For this connection, a driver for CP210x should be installed. The driver can be
downloaded from
http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx
.
A dedicated reset push button (SW1) is provided for resetting the PoE controller. The board consists of
eight output ports, of which four are 2-pair ports and the remaining four are 4-pair ports.
The board consists of different test points (for more information about test points, see
Test Points (see
page )
). The board also provides different LED indications (for more information on LED indications,
see
LED Indication (see page 6)
).
