KCU1250 Board Features and Operation
Default Jumper and Switch Positions
A list of jumpers and switches and their required positions for normal board operation is
provided in
Appendix A, Default Jumper Settings
.
Monitoring Voltage and Current
Voltage and current monitoring and control for the Maxim power system is available
through either the KCU1250 system controller or via the Maxim PowerTool™ software
graphical user interface.
The KCU1250 system controller is the simplest and most convenient way to monitor the
voltage and current values for the power rails listed in
. For details on how to use
this built-in feature, see
Power Monitoring Data Menu in Appendix D
The KCU1250 board includes these PMBus connectors:
), for use with the Maxim USB-to-PMBus interface dongle
(MAXPOWERTOOL002
) and the InTune Digital Power GUI.
• J4 (callout 21,
) is used to connect to the MGT power module PMBus using
the vendor's application tool (for example, Texas Instruments USB-to-GPIO interface
adaptor (EVM-P960
) and the Fusion Digital Power GUI).
The onboard Maxim power controllers (U23, U24, U26, U27, U28, U29, U30, and U31) by
default are isolated from the MGT power modules PMBus. However, the two interfaces can
be linked by removing J8 next to the MGT power module PMBus connector J4. This
configuration is required when using a Maxim MGT power module to allow for monitoring
and controlling both FPGA power rails and the transceiver power rails using the Maxim
InTune Digital Power GUI.
