Resolved. 0x3 corresponds to the JESD204B lanes never being driven by the FPGA due to a faulty constraint file not properly mapping the pins on the FMC connector.

Joachim, Thanks! I keep in mind we need to bypass the PGA in case of a unipolar analog supply. How about in case of a bipolar analog supply? We still need to bypass the PGA? Regards, Noriyuki Takahashi

You are welcome Noriyuki-san. When using a bipolar supply, you can enable the PGA in general to measure single-ended/ground-referenced signals. If you wanted to use Gain = 1 with the PGA enabled, all...
