INTRODUCTION
The AD9125 Evaluation Board connects to the Analog Devices Digital Pattern Generator (DPG) to allow for quick evaluation of the
AD9125. Control of the SPI port in the AD9125 is available through USB with accompanying PC software.
To ease the subsystem evaluation, a clock distribution chip (AD9516) and a quadrature modulator are also designed into this evaluation
board.
SOFTWARE
The AD9125 Evaluation Board is designed to receive data from a Data Patten Generator (DPG). The DAC Software Suite, plus the AD9125
Update, is required for evaluation. The DAC Software Suite is included on the Evaluation Board CD, or can be downloaded from the DPG
web site at http://www.analog.com/dpg. This will install DPGDownloader (for loading vectors into the DPG) and the AD9125 SPI
Controller application. The AD9125 Evaluation Board DPGDownloader software has an easy-to-use legacy graphical user interface (GUI),
but ACE, a newer evaluation software from ADI, is the preferred evaluation software. ACE can be downloaded from the ACE website at
https://wiki.analog.com/resources/tools-software/ace. The ACE plug-in for the evaluation board is available for download on the AD9125
eval webpage in the software section at http://www.analog.com/en/design-center/evaluation-hardware-and-software/evaluation-boards-
kits/EVAL-AD9125.html#eb-overview.
HARDWARE SETUP
Connect a +5V DC power supply to the banana jacks (P5 and P6). A clock source should be connected to the SMA jack labeled J1 (CLKIN)
and should be set to 500 MHz and 3 dBm. A second clock source should be connected to the SMA jack labeled J9 (LO_IN). This source
should be set to 1.8 GHz and 0 dBm. The AD9516 buffers this clock and distributes clock signals with proper frequencies to the AD9125
and the DPG. In order to monitor the AD9125 outputs, a spectrum analyzer should be connected to the SMA jack labeled J3 (DAC1_P) for
I channel DAC, J8 (DAC2_P) for Q channel DAC, or J6 (MOD_OUT) for the quadrature modulator output. The DPG connects through
connector P1 and P2 on the left edge of the evaluation board, and the USB cable should be connected to the mini USB connector labeled
XP2 USB on the lower left side of the board. Note that the PC software needs to be installed before connecting the USB cable to your
computer.
