Datasheet AD6645 (Analog Devices) - 17

AD6645 Data Sheet Spurious-Free Dynamic Range (SFDR) Two-Tone SFDR
The ratio of the rms signal amplitude to the rms value of the The ratio of the rms value of either input tone to the rms value peak spurious spectral component. The peak spurious component of the peak spurious component. The peak spurious component may or may not be a harmonic. May be reported in dBc (that is, may or may not be an IMD product, and may be reported in degrades as signal level is lowered) or dBFS (always related back dBc (that is, degrades as signal level is lowered) or in dBFS to converter full scale). (always related back to converter ful scale).
Two-Tone Intermodulation Distortion Rejection Worst Other Spur
The ratio of the rms value of either input tone to the rms value The ratio of the rms signal amplitude to the rms value of the of the worst third-order intermodulation product, reported in dBc. worst spurious component (excluding the second and third harmonics), reported in dBc.
