AD6644
Spurious-Free Dynamic Range (SFDR)
The ratio of the rms signal amplitude to the rms value of
the peak spurious spectral component. The peak spurious
component may or may not be a harmonic. Reported in
either dBc (that is, degrades as signal level is lowered), or
dBFS (always related back to converter full scale).
Two-Tone Intermodulation Distortion Rejection
The ratio of the rms value of either input tone to the rms value
of the worst third-order intermodulation product; reported in dBc.

Two-Tone SFDR
The ratio of the rms value of either input tone to the rms value
of the peak spurious component. The peak spurious component
may or may not be an IMD product. Reported in either dBc
(that is, degrades as signal level is lowered), or in dBFS (always
related back to converter full scale).
Worst Other Spur
The ratio of the rms signal amplitude to the rms value of the
worst spurious component (excluding the second and third
harmonics) reported in dBc.
