GTX Transceiver Power Module

The GTX transceiver power module supplies MGTAVCC and MGTAVTT voltages to the
FPGA GTX transceivers. Three GTX power modules are provided with the ML628 board
for evaluation. Any one of the three modules can be plugged into connectors J34 and J179
in the outlined and labeled power module location shown in
