Virtex-7 FPGA VC707 Evaluation Kit - VADJ Considerations


What voltage range is supported by VADJ on the Virtex-7 FPGA VC707 Evaluation Kit? How can this voltage be adjusted?


The VC707 FMC banks are HP banks, meaning they can support a supply voltage of up to 1.8V. The VADJ for VC707 can be 1.2V, 1.5V, or 1.8V. The default value for VADJ on the VC707 is 1.8V.

Voltage control is achieved as explained inthe VC707 Evaluation Board for the Virtex-7 FPGA User Guide(UG885); see the "FMC_VADJ Voltage Control" section.

The VC707 schematics, on page 1, show the Switching Module for VADJ with range 1.2V - 3.3V. This is accurate, as this switching module will still support VADJ up to 3.3V, however, the Virtex-7 bank that it is connected to will not.
