Detailed Description
7 Series GTX Transceiver Power Module
The 7 series GTX transceiver power module (callout 19, Figure 1-2) supplies MGTAVCC,
MGTAVTT and MGTVCCAUX voltages to the FPGA GTX transceivers. Three 7 series GTX
power modules from third-party vendors are provided with the VC7203 board for
evaluation. Any one of the three modules can be plugged into connectors J66 and J97 in the
outlined and labeled power module location shown in Figure 1-4.
Table 1-4 lists the nominal voltage values for the MGTAVCC, MGTAVTT and
MGTVCCAUX power rails. It also lists the maximum current rating for each rail supplied
by 7 series GTX modules included with the VC7203 board.
Each GTX transceiver rail comes with an associated jack that can be used to provide
external power. These external supply jacks are shown in Table 1-3.
Caution!
The 7 series GTX module MUST be removed when providing external power to the GTX
transceiver rails.
Information about the 7 series GTX power supply modules included with the VC7203 kit is
available from the vendor websites [Ref 3].
Active Heatsink Power Connector
Callout 22, Figure 1-2
An active heatsink (Figure 1-5) is provided for the FPGA. A 12V fan is affixed to the
heatsink and is powered from the 3-pin friction lock header J121 (Figure 1-6).
