Application Note 1434
Runtime X.X Installer Information window, click OK. The
InstallShield Wizard Completed window appears.
9. In the InstallShield Wizard Completed window, click Finish.
The MATLAB component runtime installation is now complete.
Running the Intersil Konverter Analyzer
Software
To run the Intersil Konverter Analyzer software:
1. On the desktop, double-click the Intersil Konverter Analyzer
shortcut icon. The application uncompresses the first time it
runs; subsequently, it starts immediately.
2. If the Welcome to the Found New Hardware Wizard window
opens, click the No, not this time radio button and then click
Next.
3. If the Hardware Installation window opens, click Continue
Anyway.
Specifications Definitions
Analog Input Bandwidth is the analog input frequency at which
the spectral output power at the fundamental frequency (as
determined by FFT analysis) is reduced by 3dB from its
low-frequency value. This is also referred to as Full Power
Bandwidth.
Aperture Delay or Sampling Delay is the time required after the
rise of the clock input for the sampling switch to open, at which
time the signal is held for conversion.
Aperture Jitter is the RMS variation in aperture delay for a set of
samples.
Clock Duty Cycle is the ratio of the time the clock wave is at logic
high to the total time of one clock period.
Differential Non-Linearity (DNL) is the deviation of any code width
from an ideal 1 LSB step.
Effective Number of Bits (ENOB) is an alternate method of
specifying Signal to Noise-and-Distortion Ratio (SINAD). In dB, it is
calculated as: ENOB = (SINAD - 1.76)/6.02
Integral Non-Linearity (INL) is the deviation of each individual
code from a line drawn from zero (1/2 LSB below the first code
transition) through positive full-scale (1/2 LSB above the last
6
code transition). The deviation of any given code from this line is
measured from the center of that code.
Least Significant Bit (LSB) is the bit that has the smallest value or
weight in a digital word. Its value in terms of input voltage is
V FS /2 N-1 where N is the resolution in bits.
Missing Codes are output codes that are skipped and will never
appear at the ADC output. These codes cannot be reached with
any input value.
Most Significant Bit (MSB) is the bit that has the largest value or
weight. Its value in terms of input voltage is V FS /2.
Pipeline Delay is the number of clock cycles between the
initiation of a conversion and the appearance of the data at the
output pins.
Power Supply Rejection Ratio (PSRR) is the ratio of a change in
input offset voltage to a change in power supply voltage.
Signal to Noise-and-Distortion (SINAD) is the ratio of the RMS
signal amplitude to the RMS value of the sum of all other
spectral components below one-half the clock frequency,
including harmonics but excluding DC.
Signal-to-Noise Ratio (without Harmonics) is the ratio of the RMS
signal amplitude to the sum of all other spectral components
below one-half the sampling frequency, excluding harmonics and
DC.
Spurious-Free-Dynamic Range (SFDR) is the ratio of the RMS
signal amplitude to the RMS value of the peak spurious spectral
component. The peak spurious spectral component may or may
not be a harmonic.
Appendix A
Source Requirements
Source jitter and noise will degrade performance. For best test
results, a combined jitter (for both clock and signal sources) that
does not exceed 200fs is recommended.
Sample Clock and Input Signal Source Setup
Sample clock settings:
? 50MHz to 500MHz sine, +10dBm
Signal settings:
? 0.4MHz to 250MHz, +7dBm to +10dBm (depending on analog
input attenuation)
