That's kinda odd now that I think about it, I had a similar problem
and on an oscilloscope it looked like DAC clipping, but I could have
been non-linearity in the final amp, what kind of problems do
XCVR2450 have at high outputs?
All amplifiers will have non-linear operating regions up near their
maximum output power. Clipping in the DAC shouldn't be approached until
the signal magnitudes approach +/- 1.0.
I don't believe the XCVR2450 is special in this regard.
