SFDR is the ratio of RMS amplitude of the carrier fre-
quency (maximum signal components) to the RMS
value of their next-largest distortion component. SFDR
is usually measured in dBc and with respect to the car-
rier frequency amplitude or in dB FS with respect to the
DAC’s full-scale range. Depending on its test condition,
SFDR is observed within a predefined window or
to Nyquist.
The two-tone IMD is the ratio expressed in dBc (or dB FS)
of either input tone to the worst 3rd-order (or higher) IMD
products. Note that 2nd-order IMD products usually fall at
frequencies that can be easily removed by digital filtering;
therefore, they are not as critical as 3rd-order IMDs. The
two-tone IMD performance of the MAX5885 was tested
with the two individual input tone levels set to at least
-6dB FS and the four-tone performance was tested
according to the GSM model at an output frequency of
32MHz and amplitude of -12dB FS.

Commonly used in combination with W-CDMA, ACLR
reflects the leakage power ratio in dB between the
measured power within a channel relative to its adja-
cent channel. ACLR provides a quantifiable method of
determining out-of-band spectral energy and its influ-
ence on an adjacent channel when a bandwidth-limited
RF signal passes through a nonlinear device.
