ZCU106 Board User Guide 115UG1244 (v1.0) March 28, 2018 www.xilinx.comChapter 3: Board Component DescriptionsCooling Fan Connector[Figure 2-1, near callout 10]The ZCU106 cooling fan connector is shown in Figure 3-43.The ZCU106 uses the Maxim MAX6643 fan controller, which autonomously controls the fanspeed by controlling the pulse width modulation (PWM) signal to the fan based on the dietemperature sensed via the FPGA's DXP and DXN pins. The fan rotates slowly (acousticallyquiet) when the FPGA is cool and rotates faster as the FPGA heats up (acoustically noisy).The fan speed (PWM) versus the FPGA die temperature algorithm along with the overtemperature set point and fan failure alarm mechanisms are defined by the strappingresistors on the MAX6643 device. The over temperature and fan failures alarms can bemonitored by the any available processor in the FPGA by polling the I2C expander, U97. Seethe MAX6643 [Ref 22] data sheet for more information on the device circuit implementationon this board.Note: At initial power on, it is normal for the fan controller to energize at full speed for a fewseconds.X-Ref Target - Figure 3-43Figure 3-43: ZCU106 12V Fan ControllerX19203-052417Send Feedback |
