DEFINITIONS OF SPECIFIED PARAMETERS
STATIC PARAMETERS
Static measurements are performed through
method of histograms on a 2MHz input signal,
sampled at 40Msps, which is high enough to fully
characterize the test frequency response. The
input level is +1dBFS to saturate the signal.
Differential Non Linearity (DNL)
The average deviation of any output code width
from the ideal code width of 1LSB.
Integral Non linearity (INL)
An ideal converter presents a transfer function as
being the straight line fromthe starting code to the
ending code. The INL is the deviation for each
transition from this ideal curve.
DYNAMIC PARAMETERS
Dynamic
spectral analysis, applied to an input sinewave of
various frequencies and sampled at 40Msps.
measurements
are
performed
by
Spurious Free Dynamic Range (SFDR)
The ratio between the amplitude of fundamental
tone (signal power) and the power of the worst
spurious signal (not always an harmonic) over the
full Nyquist band. It is expressed in dBc.
Total Harmonic Distortion (THD)
The ratio of the rms sum of the first five harmonic
distortion components to the rms value of the
fundamental line. It is expressed in dB.
Signal to Noise Ratio (SNR)
The ratio of the rms value of the fundamental
component to the rms sum of all other spectral
components in the Nyquist band (f
s
/2)
excluding
DC, fundamental and the first five harmonics.
SNR is reported in dB.
Signal to Noise and Distorsion Ratio (SINAD)
Similar ratio as for SNRbut including the harmonic
distortion components in the noise figure (not DC
signal). It is expressed in dB.
From the SINAD, the Effective Number of Bits
(ENOB) can easily be deduced using the formula:
SINAD= 6.02
×
ENOB + 1.76 dB.
When the applied signal is not Full Scale (FS), but
has an A
0
amplitude, the SINAD expression
becomes:
SINAD= 6.02
×
ENOB + 1.76 dB + 20 log (2A
0
/FS)
The ENOB is expressed in bits.
Analog Input Bandwidth
The maximumanalog input frequency at which the
spectral response of a full power signal is reduced
by 3dB. Higher values can be achieved with
smaller input levels.
Effective Resolution Bandwidth (ERB)
The band of input signal frequencies that the ADC
is intended to convert without loosing linearity i.e.
the maximum analog input frequency at which the
SINAD is decreased by 3dB or the ENOB by 1/2
bit.
Pipeline delay
Delay between time when the analog input is
initially sampled and time when thecorresponding
digital data output is valid on the output bus. Also
called data latency. Itis expressed as a number of
clock cycles.
