Virtex-7 FPGA VC707 Evaluation Kit - DCI standards in Bank 34

Description

What standards are compatible with DCI in Bank 34 on the Virtex-7 FPGA VC707 Evaluation Kit? Are there any limitations?

Solution

Bank 34 of the VC707 includes pins that form part of the FMC interface. VRN of Bank 34 is connected to the 1.8V FPGA supply via the reference resistor.

Bank 34 also includes VADJ_FPGA, a variable voltage (1.2V - 1.8V) coming from the FMC mezzanine card connected to the VC707 FMC connector. While VADJ_FPGA is variable, VRN of the bank is pulled up to a fixed 1.8V voltage, meaning DCI standards used in this bank are limited to 1.8V standards.

The 1.0 version of the VC707 Board only supports DCI when VADJ = 1.8V (factory default).

You can use VADJ at 1.5V; the FPGA will not be damaged over the lifecycle of the evaluation board, however, the use of DCI is not available in this scenario.
You can use VADJ at 1.2V; the FPGA will not be damaged over the lifecycle of the evaluation board, however, the use of DCI is not available in this scenario.
