TERMINOLOGY
Analog Bandwidth
The 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
The delay between a differential crossing of the ENCODEA
signal and the ENCODEA signal and the instant at which the
analog input is sampled.
Aperture Uncertainty (Jitter)
The sample-to-sample variation in aperture delay.
Differential Analog Input Resistance, Differential Analog
Input Capacitance, and Differential Analog Input Impedance
The real and complex impedances measured at each analog
input port. The resistance is measured statically, and the
capacitance and differential input impedances are measured
with a network analyzer.
Differential Analog Input Voltage Range
The peak-to-peak differential voltage that must be applied to
the converter to generate a full-scale response. Peak differential
voltage is computed by observing the voltage from the other
pin, which is 180 degrees out of phase. Peak-to-peak differential
is computed by rotating the input phase 180 degrees and taking
the peak measurement again. The difference is then computed
between both peak measurements.
Differential Nonlinearity
The deviation of any code from an ideal 1 LSB step.
ENCODE Pulse Width/Duty Cycle
Pulse width high is the minimum amount of time that the
ENCODE pulse should be left in a Logic 1 state to achieve the
rated performance. Pulse width low is the minimum time the
ENCODE pulse should be left in a low state. At a given clock
rate, these specifications define an acceptable encode duty cycle.
Harmonic Distortion
The ratio of the rms signal amplitude to the rms value of the
worst harmonic component.
Integral Nonlinearity
The 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
The 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
The encode rate at which parametric testing is performed.
Output Propagation Delay
The delay between a differential crossing of the ENCODEA
signal and the ENCODEA signal and the time at which all
output data bits are within valid logic levels.
Overvoltage Recovery Time
The amount of time required for the converter to recover to
0.02% accuracy after an analog input signal of the specified
percentage of full scale is reduced to midscale.
Power Supply Rejection Ratio
The ratio of a change in input offset voltage to a change in
power supply voltage.
Signal-to-Noise-and-Distortion (SINAD)
The 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. SINAD can be
reported in dB (that is, degrades as signal level is lowered) or
in dBFS (always related back to converter full scale).
Signal-to-Noise Ratio (SNR) (Without Harmonics)
The ratio of the rms signal amplitude (set at 1 dB below full
scale) to the rms value of the sum of all other spectral com-
ponents, excluding the first five harmonics and dc. SNR can be
reported in dB (that is, degrades as signal level is lowered) or
in dBFS (always related back to converter full scale).
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.
Transient Response
The time required for the converter to achieve 0.02% accuracy
when a one-half full-scale step function is applied to the analog
input.
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.
