Description
MGTVCCAUX is the auxiliary analog LCPLL voltage supply for the
transceivers. Most packages have multiple groups of power supply
connections in the package for MGTVCCAUX. Refer to the package
pin definitions to identify in which power supply group a specific
GTM transceiver Dual is located. The nominal voltage is 1.8 VDC.
VCCINT_GT is the supply voltage for digital circuits in GTM
transceivers. Most packages have multiple groups of power supply
connections for VCCINT_GT. Refer to the package pin definitions to
identify the location of the power supply group for a specific GTM
transceiver Dual. The nominal voltage is 0.9 VDC or 0.85 VDC
depending on the speed grade. See the UltraScale+ device data
sheets (see http://www.xilinx.com/documentation) for details.
