MGT Transceiver Power Module
There are two MGT transceiver power modules (callout 20 and 21,
Figure 2-1
). The GTY
power modules supply the MGTAVCC_L, MGTAVTT_L, and MGTVCCAUX_L power rails, which
connect to the FPGA GTY transceivers. The GTH power module supplies the MGTAVCC_R,
MGTAVTT_R, and MGTVCCAUX_R power rails, which connect to the FPGA GTH transceivers.
Two MGT power modules from Maxim Integrated are provided with the VCU1287 board for
evaluation. The modules can be plugged into connectors J138 and J93 or J46 and J124 in
the outlined and labeled power module locations shown in
Figure 3-3
and
Figure 3-4
.
Table 3-3
lists the nominal voltage values for MGTAVCC_L, MGTAVTT_L, MGTVCCAUX_L,
MGTAVCC_R, MGTAVTT_R, and MGTVCCAUX_R power rails. It also lists the maximum current
rating for each rail supplied by MGT modules included with the VCU1287 board.
