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.
