Virtex-7 HT FPGA GTZ Transceiver - VMGTZAVCC and VMGTZVCCL for Initial ES Silicon


This answer record covers the VMGTZAVCC and VMGTZVCCL specifications in the Virtex-7 HT FPGAs Data Sheet: DC and AC Switching Characteristics (DS184) and the values to be used for the Initial Engineering Sample (Initial ES) silicon.


The Virtex-7 HT FPGAs Data Sheet: DC and AC Switching Characteristics (DS184, v1.1) shows the specifications for both VMGTZAVCC and VMGTZVCCL as 1.075V +/- 25mV (typical 1.075V, min 1.05V and max 1.1V).  These values have been updated from 1.025V +/- 25mV. The new specifications are required only for General ES and Production silicon. For Initial ES silicon, the original values still apply or the new values can also be used for migration purposes.
