Gth Transceiver Power Module - Xilinx ML628 User Manual

Disabling Onboard Power
Voltage regulators U10, U12, U13, U22, U23, and U41 are disabled by installing a jumper at
J289 (TI PWR INHIBIT). Voltage regulator U31 is disabled by installing a jumper across
pins 2 – 3 of header J24 (AUX POR - RESET).
Default Jumper Positions
A list of shunts and shorting plugs and their required positions for normal board operation
is provided in
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). The three onboard
TI power controllers (U8 at PMBUS address 52, U19 at PMBUS address 53, and U32 at
PMBUS address 54) are wired to the same PMBus. The PMBus connector, J14, is provided
for use with the TI USB Interface Adapter PMBus pod and associated TI GUI.

GTH Transceiver Power Module

The GTH transceiver power module supplies MGTHAVCC, MGTHAVCCRX,
MGTHAVTT and MGTHAVCCPLL voltages to the FPGA GTH transceivers. Two GTH
power modules are provided with the ML628 board for evaluation. Either of the modules
can be plugged into the connectors J6 and J197 in the outlined and labeled power module
location shown in
Note:
modules from being connected to the GTX headers and vice versa.
