DE FINIT ION OF SPE CIFICAT IONS
Analog Bandwidth (Small Signal)
T he analog input frequency at which the spectral power of the
fundamental frequency (as determined by the FFT analysis) is
reduced by 3 dB.
Aperture Delay
T he delay between a differential crossing of ENCODE and
ENCODE
and the instant at which the analog input is sampled.
Aperture Uncertainty (Jitter)
T he sample-to-sample variation in aperture delay.
Differential Nonlinearity
T he deviation of any code from an ideal 1 LSB step.
E ncode Pulsewidth/Duty Cycle
Pulsewidth high is the minimum amount of time that the EN-
CODE pulse should be left in logic “1” state to achieve rated
performance; pulsewidth low is the minimum time ENCODE
pulse should be left in low state. At a given clock rate, these
specs define an acceptable Encode duty cycle.
Integral Nonlinearity
T he deviation of the transfer function from a reference line
measured in fractions of 1 LSB using a “best straight line”
determined by a least square curve fit.
Minimum Conversion Rate
T he encode rate at which the SNR of the lowest analog signal
frequency drops by no more than 3 dB below the guaranteed
limit.
Maximum Conversion Rate
T he encode rate at which parametric testing is performed.
Output Propagation Delay
T he delay between a differential crossing of ENCODE and
ENCODE
and the time when all output data bits are within
valid logic levels.
Power Supply Rejection Ratio
T he ratio of a change in input offset voltage to a change in
power supply voltage.
Signal-to-Noise-and-Distortion (SINAD)
T he ratio of the rms signal amplitude (set at 1 dB below full
scale) to the rms value of the sum of all other spectral compo-
nents, including harmonics but excluding dc.
Signal-to-Noise Ratio (SNR)
T he ratio of the rms signal amplitude (set at 1 dB below full
scale) to the rms value of the sum of all other spectral compo-
nents, excluding the first five harmonics and dc.
Spurious-Free Dynamic Range (SFDR)
T he ratio of the rms signal amplitude to the rms value of the
peak spurious spectral component. T he peak spurious compo-
nent may or may not be a harmonic. May be reported in dBc
(i.e., degrades as signal levels is lowered), or in dBFS (always
related back to converter full scale).
T wo-T one Intermodulation Distortion Rejection
T he ratio of the rms value of either input tone to the rms
value of the worst third order intermodulation product; re-
ported in dBc.
T wo-T one SFDR
T he ratio of the rms value of either input tone to the rms value
of the peak spurious component. T he peak spurious component
may or may not be an IMD product. May be reported in dBc
(i.e., degrades as signal levels is lowered), or in dBFS (always
related back to converter full scale).
Worst Harmonic
T he ratio of the rms signal amplitude to the rms value of the
worst harmonic component, reported in dBc.
