DNA Data
This data is stored in the SYZYGY DNA microcontroller on the SZG-DUALSFP peripheral.
Note that the maximum 3.3V load below is an overestimate due to the variability in power consumption between SFP modules.

Eye Diagrams
Several eye diagrams were taken using Xilinx’s iBERT tool to empirically test the quality of the link.
Test conditions and setup:
- Vivado 2017.2
- iBERT version 3.0 (Rev. 15)
- Brain-1 used as the carrier
- Peripheral contained two Finisar FTL8524P2BNV SFP transceivers
- Scans performed at 3.75Gbps
