8-Bit to 16-Bit, 40MSPS to 500MSPS ADC Evaluation System
AN1434 Rev 4.00 Page 1 of 8
Mar 31, 2011
The Intersil KMB001 evaluation system allows users to
evaluate the Intersil portfolio of low-power, 8-bit to 16-bit,
high-performance analog-to-digital converters (ADC). These
converters run at sampling rates of 40MSPS to 500MSPS and
are designed with the Intersil proprietary FemtoCharge™
technology on a standard CMOS process.
The KMB001 evaluation system uses the Intersil Konverter
Analyzer software, which displays all pertinent data such as
SFDR, SINAD, ENOB, harmonics, current, and power
measurements. The software also plots outputs in frequency
spectra and time domain.
To begin testing, simply connect the input signal, sampling
clock, and target computer to the motherboard, and supply
power (Figure 1). The motherboard provides appropriate
supply voltages and captures digital data from the daughter
card. Daughter cards contain the ADCs and attach directly to
the KMB001 to form the ADC evaluation platform (Figure 2).
To ensure proper operation of the system, it is recommended
that the most current software version be installed. If Intersil
Konverter Analyzer is already installed on the machine, it must
be uninstalled prior to installation of the latest version.
Features
• 18Mb FIFO captures 1M ADC output samples
• USB2.0 interface for rapid data transfer
• Datasheet-style, live-updated display
KMB001 Evaluation System
Contents

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
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
VFS/2N-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 VFS/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)

4. You shall not alter, modify, copy, or reverse engineer any Renesas Electronics product, whether in whole or in part. Renesas Electronics disclaims any and all liability for any losses or damages incurred by
you or third parties arising from such alteration, modification, copying or reverse engineering.
5. Renesas Electronics products are classified according to the following two quality grades: “Standard” and “High Quality”. The intended applications for each Renesas Electronics product depends on the
product’s quality grade, as indicated below.
"Standard": Computers; office equipment; communications equipment; test and measurement equipment; audio and visual equipment; home electronic appliances; machine tools; personal electronic
equipment; industrial robots; etc.
"High Quality": Transportation equipment (automobiles, trains, ships, etc.); traffic control (traffic lights); large-scale communication equipment; key financial terminal systems; safety control equipment; etc.
Unless expressly designated as a high reliability product or a product for harsh environments in a Renesas Electronics data sheet or other Renesas Electronics document, Renesas Electronics products are
not intended or authorized for use in products or systems that may pose a direct threat to human life or bodily injury (artificial life support devices or systems; surgical implantations; etc.), or may cause
serious property damage (space system; undersea repeaters; nuclear power control systems; aircraft control systems; key plant systems; military equipment; etc.). Renesas Electronics disclaims any and all
liability for any damages or losses incurred by you or any third parties arising from the use of any Renesas Electronics product that is inconsistent with any Renesas Electronics data sheet, user’s manual or
