Are there any known-issues/errata with the FMC151 DAC outputs? We are seeing that any waveform that we output on DAC 'C' is inverted from the original waveform that we send. However, the waveform on DAC output 'D' is correct (i.e. not inverted).
DAC 'C' ==> O-scope ==> inverted
Same Waveform ==<
DAC 'D' ==> O-scope ==> _not_ inverted
It seems as if somehow the differential P/N pairs were hooked up incorrectly on the board for DAC 'C'.
Running the identical FPGA design and FMC150App with the FMC150 card does not have this issue. So therefore it has to be an issue with the FMC151.
