The Recalibrate menu item resets the ADC, which forces
a recalibration. The GUI will automatically recalibrate the
ADC when the clock frequency changes if
Setup→AutoRecal is selected.
The Prom Programmer menu item is a password
protected factory function and is not intended for general
usage.
Register Edit allows access to the entire SPI register
map. An example is shown in Figure 12. Refer to the
product datasheet for specific register definitions.
Help
The Diagnostic Dump menu item saves detailed status
information that can be used by the factory to help
troubleshoot operational issues.
About shows version information and can display the
software license agreement.
System Info displays information about the software and
hardware set-up.
Toolbar
Zoom
Selecting one of the magnifying glass icons allows the
axis limits to be changed graphically. Right click in the
graph window for zoom options (horizontal or vertical) or
to reset the axes to default limits.
Pan
The hand icon allows panning the graphic when zoomed.

Markers
Data points can be marked by selecting the marker icon
and clicking on the graphic. Multiple markers can be
placed by selecting Create New Data tip from the
right-click menu. X and Y data is displayed for each
marker.
Appendix A: RF Generators
Intersil uses the following RF generators as clock and
signal sources when characterizing high-speed ADCs:
• Rohde & Schwarz: SMA100A
• Agilent: 8644B (with Low-Noise option)
These generators provide very low jitter to optimize the
SNR performance of the ADC under test. Other
generators with similar phase noise performance can also
be used. Contact Intersil Technical Support for
recommendations.
Appendix B: Daughter Cards
KDC5512EVALZ, KDC5512HEVALZ,
KDC5512-50EVALZ, KDC5514EVALZ,
ISLA112P50IR72EV1Z
These daughter cards use a common design to
accommodate the single-input devices from the
KAD55XX and ISLA11XP50 families. They allow for two
clock input paths and two analog input paths. The clock
can be driven through a 4:1 transformer or a CML buffer.
The default clock path is through the Mini-Circuits
TC4-1W transformer (labeled as CLOCK INPUT XFMR on
the PCB). The AC-coupling capacitors in the buffered
path (C46, C47) are not populated. To use the clock
buffer, install 200pF capacitors in positions C46 and C47
and depopulate the AC-coupling capacitors (C28, C29) in
the transformer path.
