MAX5855 Evaluation Kit
Evaluates: MAX5855
General Description
The MAX5855 evaluation kit (EV kit) contains a single
MAX5855 wideband interpolating and modulating RF
digital-to-analog converter (DAC) which can directly
synthesize 1GHz of instantaneous bandwidth from DC
to frequencies greater than 2.3GHz. The MAX5855 EV
kit provides a complete system for evaluating MAX5855
performance as well as developing a FPGA plus DAC
transmitter solution.
The MAX5855 accepts input data through a five-lane
JESD204B serializer/deserializer (SerDes) interface at
9.8304Gbps that is Subclass-0 compliant. The MAX5855
EV kit connects to one FMC connector on the Xilinx
VC707 evaluation kit, allowing the VC707 to communicate
with the MAX5855’s JESD204B serial link interface.
The evaluation kit includes Windows
®
7/10-compatible
software that provides a simple graphical user interface
(GUI) for configuration of all the MAX5855 registers
through the SPI interface, control of the VC707 FPGA and
temperature monitoring.

DECRIPTION
Maxim recommends using the default installation path (c:\
MaximIntegrated\MAX5855EVKIT).
If an alternate path
is desired it must NOT contain any spaces or the Xilinx
LabTools will not be accessed properly. This step should
take ~ 2 minutes. The EV kit is fully assembled and
tested. Follow the steps below to verify board operation:
Required Software and Drivers
Initial Setup
Required Equipment
●
Window PC (Win-7, Win-10), with one or two
available USB 2.0 ports
●
Spectrum Analyzer (Agilent PXA or equivalent)
●
RF signal generator (R & S
®
SMF100A or equivalent)
●
3.3V, 4A power supply for MAX5855 EV kit
●
User-supplied Xilinx VC707 EV kit
• VC707 board.
• 12V/5A power cube.
• 1 each USB-A to Mini-B cable for interfacing with
the VC707 and MAX5855.
• 1 each USB-A to Micro-B cable for programming
the VC707.
●
Low-loss SMA/SMA cables as needed for connections
to the Spectrum Analyzer and Signal Generator
●
Included in the MAX5855 EV kit
• MAX5855 Evaluation Kit board.
•
Two 1” stand-offs with screws.
• USB-A to Mini-B cable, for interfacing with the
VC707/MAX5855 or directly to the EV kit board.
The MAX5855 EV kit software controller application
requires the following third-party software components
and drivers to be installed.
Refer to
Appendix I
of this
document for additional information on this installation
process.
It is highly recommended that the target PC be
connected to a local area network and have access to the
Internet, this allows for automatic download and updates
of some drivers. This process may take
30 minutes
or
more to complete.
●
Xilinx ISE 14.7 LabTools
This is a free tool set used for programming the
VC707 evaluation board. No software license is
required to use these tools. However, a Xilinx Login
will be required for downloading.
●
Xilinx Drivers
After the LabTools have been installed on a PC, the
VC707 USB interface drivers can be installed.
●
LIB USB Driver
Manual installation of this driver is required after the
VC707 is programmed enabling the USB 2.0 bulk
transfer port.
●
Microsoft .NET Framework 4
The Microsoft .NET Framework 4 is required by the
MAX5855EVKITsoftwareController
application. The
Win-7 operating system requires manually installing
the .NET Framework package using the installer cop-
ied to the
{installationpath}\MAX5855EVKIT\AppFiles\
ThirdParty
during the EV kit software installation.

Install the MAX5855 EV kit Software
The MAX5855 EV kit Software Controller application can be
obtained from the
www.maximintegrated.com
website.
Access the
MAX5855RFDACEVKitSoftwareInstaller.
exe
file to install the software.
Maxim recommends using the default installation path
(c:\
MaximIntegrated\MAX5855EVKIT).
If an alternate path
is desired, it must NOT contain any spaces or the Xilinx
LabTools will not be accessed properly. This step should
take less than
2 minutes.
6) Turn on the VC707 by sliding the VC707 Main Power
Switch (SW12) to the ON position. Verify ALL the LEDs
on the VC707 are momentarily lit; the GPIO LEDs
should then begin sequencing.
7) Make the USB connections, see
Figure 1
for locations
a. Connect the USB A – micro B cable (JTAG) from
Xilinx VC707 Eval board to the PC
b. Connect the USB A – mini B cable (Ctrl/Bulk) from
Xilinx VC707 Eval board to the PC
Please ensure that all the required third-party software
and drivers are installed before proceeding to the next
section.
Setup and Connect the MAX5855 EV
Kit Hardware
1) Install the two 1” stand-offs included with the MAX5855
EV kit. Stand-offs should be installed on the RF DAC
output side of the board.
2) Verify all jumpers on the MAX5855 EV kit board are in
the default position; refer to
Table 1.
3) Connect the MAX5855 EV kit board to the VC707
board using the FMC Interface connector shown, as
shown in
Figure 1.
4) Connect the 3.3V/4A supply to the MAX5855 EV kit
board and enable the supply’s output. Verify the four,
green, LED board supply indicators are lit.
5) Connect the RF generator to the CLK Input with a low-
loss SMA cable and set the frequency to 491.52MHz
with output power at +2dBm, and enable the output.
Configure the MAX5855 EV kit
Graphical User Interface
A few items need to be configured during the first execution
of the GUI software.
1) Start the MAX5855 EV kit software. Double-click
on the desktop icon or the
MAX5855EVKITsoft
wareController.exe
executable located in the
C:\
MaximIntegrated\MAX5855EVKIT
folder. A splash
screen will be displayed while the USB connections
are established (Figure
2)
followed by the window
shown in
Figure 3.
2) Click the <SPI Communication to DAC from FPGA>
button and the primary GUI software window will be
loaded (see
Figure 4).
