Microsemi’s PD70211EVB50FW Evaluation Board (see
Figure 2) provides designers with an environment needed for evaluating the performance and implementation of
PD applications based on PD70211 controller.
The board is using a single PD controller, PD70211ILQ, to support the Detection, Class, and Power Supplying
phases on the 4 Pairs of the Cat5 cable. The board supports sync detection of the 4 pairs. PD70211ILQ supports
the current of the HDBaseT over 4 Pairs, which is more than twice the power of a standard IEEE802.3AT Type 2
interface.
All necessary steps and connection instructions required to install and operate this board are provided within this
document.

3.3 Indications
The following sections provide general information regarding unit’s indications.
1. LED Indication
See Figure 5.
3.3.1.1 LED Indication
See Figure 5.
D16 is the AT_FLAG indication LED, a PD70211 device output signal indicating the device has detected a 2 finger
class event from the PSE side in the class stage. The flag will be operative at 3, 4, and 6 fingers detection as well.
D15 is the 4P_AT indication LED, a PD70211 device output signal indicating the device has detected a 4 finger
class event from the PSE side in the class stage, or a 2 finger class event from the PSE side in the class stage,
and SUPP_Sa and SUPP_Sb are both High.
The flag will be operative at 6 fingers detection as well.
D20 is the HD_FLAG indication LED, a PD70211 device output signal indicating the device has detected a 3 finger
class event from the PSE side in the class stage.
The flag will be operative at 6 fingers detection as well.
D19 is the 4P_HD indication LED, a PD70211 device output signal indicating the device has detected a 6 finger
class event from the PSE side in the class stage.
D14 is the Power Good indication. This LED indicates the presence of power. This indicator may be configured to
monitor PD Front End VAUX (Asserts when VPP = 36V min.; de-asserts when VPP = 31V min.), or it may be
configured to monitor the VPP UVLO, which is user selectable by the resistor values at VINS and HYST pins (R13,
R19, and R25). See the PD70211 datasheet for further details regarding setting VPP UVLO limits. EVB default for
Power Good EVB is monitoring VPP UVLO, and will track the operation of the DC-DC converter. To change Power
Good to monitor PD Front End VAUX:
1) Remove R51, 100 Ohm Resistor (located on PCB bottom under D10).
2) Add R50 Zero Ohm Jumper (Also located on PCB bottom under D10).
3) Insure that only R51 or R50 are installed; do not operate with both resistors installed.

5 Installation
5.1 Preliminary Considerations and Safety Precautions
If using an external supply in place of a PSE, verify the external power supply is turned “off”
before all peripheral devices are connected. Insure the external supply is connected to the
RJ45 input (J1) per Table 3.
5.2 Initial Configuration
Note: It is important to verify evaluation board is setup as shown in Figure 6 prior to starting any operation.
1. Connect load to evaluation board (J3 -1 (+) & J3 –2 (-), or TP17 (+) & TP16 (-)).
2. Connect a Cat5 cable from PSE to Evaluation Board (J1), or a 48V Wall Adapter to Evaluation Board (J2).
Note: Wall Adapter will override power from PSE.
