Gtp Transceiver Power Module - Xilinx SP623 User Manual

Monitoring Voltage and Current
Voltage and current monitoring and control are available for selected power rails through
Texas Instruments' Fusion Digital Power graphical user interface (GUI). Both onboard TI
power controllers are wired to the same PMBus. The PMBus connector, J6, is provided for
use with the TI USB Interface Adapter PMBus pod and associated TI GUI.

GTP Transceiver Power Module

The GTP transceiver power module supplies MGTAVCC and MGTAVTT voltages to the
FPGA GTP transceivers. Two power modules are provided with the SP623 board. Either of
the power modules can be plugged into connectors J34 and J179 in the outlined and labeled
power module location shown in

The GTP transceiver power rails also have corresponding input voltage jacks to supply
each voltage independently from a bench-top power supply (See External Supply Jack
