Gtx Transceiver Power Module - Xilinx ML623 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.

GTX Transceiver Power Module

The GTX transceiver power module supplies MGTAVCC and MGTAVTT voltages to the
FPGA GTX transceivers. Three power modules are provided with the ML623 board. Any
one of the three modules can be plugged into connectors J34 and J179 in the outlined and
labeled power module location shown in

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