CAUTION! When supplying 12V through J28, use only the power supply provided for use with this board (Xilinx
part number 3800033).
CAUTION! Do NOT use a 6-pin, PC ATX power supply connector with J28. The pinout of the 6-pin, PC ATX
connector is not compatible with J28 and the board will be damaged if an attempt is made to power it from a PC
ATX power supply connector.
12V power can also be provided through:
• Connector J73 (callout 4,
drive 4-pin power plug
• Connector J27 (callout 3,
bench-top power supply
CAUTION! Because connector J73 provides no reverse polarity protection, use a power supply with a current
limit set at 6A maximum.
CAUTION! Do NOT apply 12V power to more than a single input source. For example, do not apply power to
J73 and J27 at the same time.
CAUTION! If J73 or J27 is used to supply the 12V input power, be careful that board power consumption does
not exceed 75W (this includes the RFSoC).
