GENERAL DESCRIPTION
This user guide describes the AD9081-FMCA-EBZ, AD9082-
FMCA-EBZ, AD9986-FMCB-EBZ, and AD9988-FMCB-EBZ
evaluation boards, which provide all of the support circuitry
required to operate the AD9081, AD9082, AD9986, AD9988,
AD9207, AD9209, or AD9177 in their various modes and
configurations. The application software used to interface with
the devices is also described. These evaluation boards connect
to the Analog Devices, Inc., ADS9-V2EBZ for evaluation with
the ACE software.
These evaluation boards can also interface to commercially
available field-programmable gate array (FPGA) development
boards from Xilinx® or Intel®. Information on how to use these
platforms to evaluate the AD9081 or the AD9082 is available in
the Using the AD-FMC-SDCARD section.
The ACE software allows the user to set up the MxFE® in
various modes and to capture analog-to-digital converter
(ADC) data for analysis. The DPGDownloaderLite software
(included in ACE installation) generates and transmits vectors
to the digital-to-analog converters (DACs), which can then be
sent to a spectrum analyzer for further analysis.
For additional information, see the AD9081, AD9082, AD9986,
AD9988, AD9207, AD9209, or AD9177 data sheets and the
UG-1578, the device user guide, which must be consulted in
conjunction with this user guide when using the evaluation
boards.

EVALUATION BOARD OVERVIEW
BOARD MODELS
The different board models are all listed in Table 1.
Certain early revisions of the evaluation boards shipped with a
122.88 MHz on-board crystal oscillator. The ACE plugin is
designed to detect the evaluation board and make it function
appropriately.
EVALUATION BOARD CONNECTION OVERVIEW
Figure 5 shows the basic hardware setup required to evaluate
the AD9081, AD9082, AD9986, or AD9988. Note that the
AD9082-FMCA-EBZ is shown in Figure 5 as an example. This
setup uses the on-board clock to manage the clocks for the
AD9082 as well as the FPGA for proper functioning of the
transceivers.

INSTALLATION OF HEAT SINK WITH INTEGRATED FAN
A heat sink (with integrated fan) is shipped with each
evaluation board for active cooling of the IC. Note that the
power consumption of the IC is dependent on its operation
mode with some configurations consuming up to 13 W, where
the IC die temperature can approach or exceed its maximum
specified operating range of 120°C. Therefore, it is recommended
to install the heat sink shown in Figure 6 through Figure 8
before the evaluation process begins.
The heat sink installation steps are as follows:
1. Remove the blue frame clip that is attached to assembly by
lifting the metal tab free from this frame clip by using a
small tweezer or a metal pick (see Figure 6). This frame
clip is not essential for attachment of the heat sink to the
IC (while noting that the AD998x-FMCB-EBZ variant does
accept this frame clip due to passive components within its
keep out region).
2. Remove the thin plastic tape to expose the adhesive surface
(see Figure 7).
3. Carefully position and center the heat sink on top of the IC
package such that it also remains clear of the RF baluns
(see Figure 8).
4. Once positioned correctly, press down on the top side of
the heat sink for 10 seconds to secure it to the IC package
(see Figure 8).
5. Connect the power supply cable (see Figure 8).
Once power is applied to the evaluation board, the fan starts
spinning. In the unlikely event that the fan does not spin, the
two screws used to secure the fan to the heat sink may be too
tight, which has resulted in the fan blades not spinning freely.
Note that loosening the screws often releases the fan blade
allowing it to spin freely.
Additional information on the Advanced Thermal Solutions
fanSink™ product can be found on the website of the company.

EVALUATION BOARD HARDWARE SETUP
DETERMINE THE CLOCK SOURCE
Determine whether the AD9081-FMCA-EBZ, AD9082-FMCA-
EBZ, AD9986-FMCB-EBZ, or AD9988-FMCB-EBZ is set to the
external clock or on-board HMC7044 clock by checking the C3D,
C4D, C5D, and C6D capacitors on the evaluation board chosen. By
default, the HMC7044 clock is enabled (C3D and C5D are
placed on the evaluation board, and C4D and C6D are do not
insert (DNI)). If using a direct external clock, remove the C3D
and C5D capacitors and place the C4D and C6D capacitors on the
evaluation board. The capacitors are 0.1 μF, size 0201 (imperial) or
size 0603 (metric). For additional details, see Figure 18 and
Figure 19.
DEFAULT CLOCKING SCHEME FOR AD9081-FMCA-
EBZ, AD9082-FMCA-EBZ, AD9986-FMCB-EBZ, OR
AD9988-FMCB-EBZ
The default clocking scheme for these evaluation boards uses
the on-chip phase-locked loop (PLL) within the AD9081, AD9082,
AD9986, or AD9988. The HMC7044 provides the reference
input to the chip. The evaluation board provides all the necessary
clocks for conducting a quick evaluation of the device, including
the auxiliary clocks needed by the FPGA in the ADS9-V2EBZ
board to set up the JESD204B or JESD204C link. The clocking
scheme is shown in Figure 20. As shown in Table 1, the reference
frequencies used by the two boards (AD908x-FMCA-EBZ or
AD998x-FMCB-EBZ) are different. Therefore, each board only
supports the integer multiples of the crystal oscillator that are
on the evaluation board. The plugin only supports the integer
multiples of the crystal oscillator that are installed on the
evaluation board. If a different clock frequency is required for
evaluation, the user must modify the evaluation board to accept
an external clock by following the instructions previously listed.
This modification also necessitates an additional clock source
for the ADS9-V2EBZ. Refer to Figure 30 for additional details
on the instrument setup.

SET UP THE INSTRUMENTATION
To use on-board clocking, the user must only provide an analog
input signal using a signal generator. To analyze DAC outputs, a
spectrum analyzer is needed.
The following are recommended instruments and connectors:
 Signal generator: a low phase noise signal generator, such
as the Rohde & Schwarz SMA (100A or 100B) or
Keysight UXG/EXG series. Note that the performance
listed in the product data sheet is from the Rohde &
Schwarz SMA100B with the B-711 option.
 Spectrum analyzer: Keysight PXA/UXA or Rohde &
Schwarz FSW/FSWP.
 Cables: use a shielded, RG-58, 50 Ω coaxial cable.
Ensure that the 10 MHz references are shared between the
instruments.
Analog Devices recommends the coaxial, 48.0 in. (1.2 m or
4.0 ft), RG316 DS, SMA to SMA, male to male cable assembly
from Cinch Connectivity Solutions Johnson, Part Number 415-
0033-048 for the setup.
Set Up the Spectrum Analyzer
Analog Devices recommends the following configuration for
the spectrum analyzer:
 Start frequency = 50 MHz (or 0 MHz)
 Stop frequency = 5 GHz
 Resolution bandwidth = 30 kHz
 Use an average or rms detector setting and set the input
attenuation to 6 dB or as desired
These settings can be changed to satisfy the particular use case.
It is recommended to have all the instruments share a common
reference. Usually, this common reference is achieved by
connecting the 10 MHz reference output from one instrument
to the reference input of the next, and so on.

USING THE AD9081, AD9082, AD9986, OR AD9988 BOARD VIEW
The board view allows the user to quickly set up the AD9081,
AD9082, AD9986, or AD9988 to a predetermined use case for
evaluation. The board view uses the on-board clocking solution
to manage the clocks to the AD9081, AD9082, AD9986, or
AD9988, as well as the FPGA. For more details on the clock
setup, refer to Figure 20. Figure 21 shows the hardware
connection needed when using the board view with the
AD9082-FMCA-EBZ board as an example.

SETTING UP THE AD9081, AD9082, AD9986, OR
AD9988 IN FULL BANDWIDTH MODE
Set up the evaluation board as explained in the Evaluation
Board Hardware Setup section. Open the board view. This
section uses the evaluation board in its default configuration with
the HMC7044 clock enabled (C3D and C5D are placed, and
C4D and C6D are DNI). See Figure 18 and Figure 19 for additional
details.
In the QUICK CONFIGURATION pane, select the
DA[email protected], AD[email protected], JESD204C (4D2A ADC Full
Bandwidth) from the Select Use Case pulldown menu (see
Figure 22), and click Apply.

ADC ANALYSIS AND DAC OUTPUT SETUP
This section explains how to use ACE for analysis of ADC data
and DPGDownloaderLite (included in ACE installation) for
sending waveforms out the DAC channels. Regardless of
whether the board view or the chip view is used, the same
procedure applies to using ACE and the DPGDownloaderLite
software.
CAPTURE AND ANALYSIS OF ADC DATA
After setting up the AD9081, AD9082, AD9986, or AD9988
using the QUICK CONFIGURATION pane in the board view,
open the ADC data analysis window by clicking the Proceed to
Analysis button in the AD9081, AD9082, AD9986, or AD9988
chip view. Set up a signal generator with a single-tone sinusoid at
1.81 GHz and ~6.5 dBm output power. Supply this signal to the
ADC0 input. Select the Waveform and FFT boxes on the left
side of the pane, and then click Run Once to run the FFT analysis
(see Figure 25). A graph displays, together with details of the
analysis. For optimum ADC performance, ensure that the correct
Nyquist zone is selected in the QUICK CONFIGURATION
options.

DAC WAVEFORM GENERATION USING
DPGDownloaderLITE SOFTWARE
To generate a waveform using the DPGDownloaderLite software,
open DPGDownloaderLite (Start > All Programs > Analog
Devices > DPGDownloaderLite) within the ACE software and
ensure the evaluation board is displaying the product number
matching the hardware used. Ensure AD9081, AD9082, AD9986,
or AD9988 is selected under Eval Board (AD9082 is shown in
Figure 26).
Next, select Single Tone from Add Generated Waveform (see
Figure 26).
