We can read it in the datasheet. Instead, please spend some time to explain the interesting and unusual things about this driver that will help reviewers understand *why* you are doing what you are doing. This is a very complex driver! In particular, on this one, the documentation on the FPGA IP block isn't very detailed. So it will be very helpful to know more about how all of the sync stuff is supposed to work and what kind of filtering is the FPGA doing in addition to the filtering done in the ADC chip.
