Please connect with iWave representative for the clock synthesizer program file for G65D platform with the Reference Clock 1 which is modified to 156.25 MHz for GTH Bank 128. Kindly note that SDI will not be supported with this change.
Additionally, please update the constraint file in the Vivado design to use Reference Clock 1 (GTREFCLK1 – pins D25 and D26) for the SFP interface from GTH Bank 128 on the G65D dev kit platform.
Please connect with iWave representative for the clock synthesizer program file and the constraint file
After making the required updates, please recompile the design and generate the updated XSA file.
Please refer section “Clock Synthesizer” in the Software User Manual to replace the clock synthesizer program file.
To clarify, Reference Clock 1 (not sourced from the FMC) supports both the SFP and SDI interfaces. Therefore, by default in G65D devkit configuration, both SFP and SDI can operate simultaneously without requiring any changes to the clock file and without the need for an FMC card.
