internal clock is always a valid option. If the external
clock is selected, an external clock must be applied at the
DCLK_IN SMA on the EV kit. The Sync-Out CLK selection
is used to synchronize the signal generator with a 10MHz
input. See the Sync Input and Sync Output section for
more information. Once the above configurations are
completed, adjust to the desired sampling rate, reference
voltage, and number of samples, and then click on the
SET button.
General Description of Software
The main window of the MAX11905 EV kit software con-
tains five tabs: SYSTEM, SCOPE, DMM, HISTOGRAM,
and FFT. The SYSTEM tab provides control to com-
municate with the ZedBoard, SPI, and the IC registers.
The other four tabs are used for evaluating the IC’s high-
speed ADC.
SYSTEM Tab
When all connections are made on the system and
are fully powered, the SYSTEM tab sheet displays the
correct IP address, port, and the lower status bar
displaysasshownFigure1.Theseareallindicatorsthatthe
system and GUI are ready for communication.
Also in this tab are the IC register controls. The Mode
register is accessible using the controls on the MAX11905
Mode Register Configuration group box in the center, or
the Mode control on the right. All other registers are read-
only and are updated by clicking on the appropriate Read
button. The first and second REF must be shorted on the
board to use the REF controls. 1st REF BUF and 2nd
REF BUF are internally set to the same value. The GUI
forces these two controls to the same value, regardless
of the user’s choice.
Before proceeding, the connector used on the ZedBoard
shouldbeconnectedtoeithertheFMCorperipheralmodule
connector on the EV kit. If the FMC connector is used, all
SCLK frequencies are applicable. If the peripheral module
connector is used, the maximum allowed frequency is
37.5MHz. For the Clock Source selection, the ZedBoard

allows counts and voltages. Once the desired configuration
is set, click on the Capture button. The right side of the tab
sheet displays details of the waveform, such as average,
standard deviation, maximum, minimum, and fundamental
frequency.
SCOPE Tab
The SCOPE tab sheet is used to capture data and display it
in the time domain. Sampling rate and number of samples
can also be set in this tab if they were not appropriately

HISTOGRAM Tab
The HISTOGRAM tab sheet is used to capture the histo-
gram of the data. Sampling rate and number of samples
can also be set in this tab if they were not appropriately
adjusted in other tabs. Make sure that the number of sam-
ples do not exceed 524,288. Otherwise, data capturing is
longer than expected. Once the desired configuration is

To use this histogram feature, apply a DC voltage at the
input. Figure 4 displays the results when the inputs of the
EV kit are shorted to ground using jumpers JU1, JU2, JU4,

To achieve the results similar to Figure 6, the daughter
board was configured to inverting configuration. Use the
jumper settings from Table 2 for proper configurations.
The input signal from the signal generator must be exactly
10000.000000 Hz. The low-jitter clock is synchronized
with the signal generator. The master clock was initially
set to 1000000000 Hz but to achieve coherent sampling,
the user must click on the Calculate button and use the
Adjusted(Hz) frequency. 99523158.694 Hz was entered
into our low-jitter clock. The master clock is fed back to
the ZedBoard and multiplied by 3/2, then generates a sys-
tem clock that drives the Xilinx FPGA. Timing for all SPI
timing and sampling rate are based off the system clock.
FFT Tab
The FFT tab sheet is used to display the FFT of the data.
Sampling rate and number of samples can also be set in
this tab if they were not appropriately adjusted in other
tabs. When coherent sampling is needed, this tab sheet
allows the user to calculate the input frequency or the
master clock coming into the board. Either adjust the
input frequency applied to the signal generator or adjust
the master applied to the DCLK_IN SMA connector. See
the Sync Input and Sync Output section before using
this feature. Once the desired configuration is set, click
on the Capture button. The right side of the tab displays
the performance based on the FFT, such as fundamental
frequency, THD, SNR, SINAD, SFDR, ENOB, and noise
floor.
If the results do not look similar to Figure 6 and more
similar to Figure 7, then check all connections in Figure 5
to make sure the setup is synchronizing properly.
Figure 5 shows the setup Maxim uses to capture data for
coherent sampling.

User-Supplied AVDD
General Description of Hardware
The AVDD supply is powered through a +1.8V LDO by
default. For user-supplied AVDD, remove the shunt on
jumper JU12 and apply +1.7V to +1.9V at jumper JU12-2.
The MAX11905 EV kit provides a proven layout to demon-
strate the performance of the MAX11905 20-bit SAR ADC.
Included in the EV kit are digital isolators, ultra-low-noise
LDOs (MAX8510) to all supply pins of the IC, on-board
reference (MAX6126), precision amplifiers (MAX9632) for
the analog inputs, and sync-in and sync-out signals for
coherent sampling.
User-Supplied DVDD
The DVDD supply is powered through a +1.8V LDO by
default. For user-supplied DVDD, remove the shunt on
jumper JU15 and apply +1.7V to +1.9V at the DVDD test
point.
User-Supplied SPI
To evaluate the EV kit with a user-supplied SPI bus,
remove shunts from jumper JU9. Apply the user-supplied
SPI signals to the SCLK, CNVST, DIN, and DOUT test
points. Make sure the return ground is the same as the
IC’s ground.
User-Supplied OVDD
The OVDD supply is powered through a +3.3V LDO by
default. For user-supplied OVDD, remove the shunt on
JU11 and apply +1.5V to +3.6V at jumper JU13-1. Since
there is a supply limitation on the isolators (U3, U18), the
OVDD supply should not be powered below +2.7V when
the FMC connector or peripheral module of the EV kit are
being used.
User-Supplied REFVDD
The REFVDD supply is powered through a +3.3V LDO by
default. For user-supplied REFVDD, remove the shunt on
jumper JU13 and apply +2.7V to +3.6V at jumper JU13-1.

inverting configuration (see Figure 10), and NONINV+
and NONINV- SMAs for noninverting configuration (see
Figure 11).
User-Supplied REFIN
The IC uses an on-board +3V reference (MAX6126) by
default. For user-supplied REFIN, move the shunt on
jumper JU14 to the 2-3 position. Make sure that REFIN
is 300mV below REFVDD before applying the reference.
The EV kit is also configurable for single-ended input to
differential (see Figure 12 and Figure 13). The desired
signal should be applied at the INV+ SMA for inverting
and at the NONINV+ SMA for noninverting. If the source
is 50Ω output impedance, then jumper JU4 must be in the
2-3 position.

Sync Input and Sync Output
Interface Connectors
The DCLK_IN SMA accepts an approximate 100MHz
waveform signal to generate the system clock of the
ZedBoard. For maximum performance, use a low-jitter
clock that syncs to the user’s analog function generator.
The SYNC_OUT SMA outputs a 10MHz square waveform
that syncs to the user’s analog function generator. Both
options are used for coherent sampling of the IC. Only
one option should be used at a time. The relationship
The EV kit and ZedBoard communicate in two ways,
using the peripheral module connector (J1) or the FMC
connector (J2) on the EV kit. The maximum SPI SCLK
frequency is 37.5MHz for the peripheral module connec-
tor and 75MHz for the FMC connector.
