Getting Started with the AD9739-R2-EBZ Evaluation Board
WHAT'S IN THE BOX
AD9739-R2-EBZ Evaluation Board
Evaluation Board CD
Mini-USB Cable
INTRODUCTION
The purpose of this document is to get the AD9739 evaluation board up and running as quickly as possible and provide guidance on how
to optimize the controllers in the part to get the optimal performance out of the AD9739.
SOFTWARE
The AD9739-R2-EBZ is designed to receive data from a DPG2. The DAC Software Suite, plus the AD9739 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 DPG2) and the AD9739 SPI application.
HARDWARE SETUP
To operate the board, a power supply capable of +5vdc, 2A should be connected to J17. A spectrum analyzer or an oscilloscope to view
the DAC output should be connected to J1. The diagram in Figure 1 shows the location of each connection. A low jitter (< 0.5psec RMS)
sine or square wave clock source should be connected to J3. The DC level of the clock is unimportant since the clock is AC-coupled on
the evaluation board before the CLKP/N inputs. The included USB cable should be used to connect the Evaluation Board to a PC. Note
that the software described above should be installed before connecting the USB cable.
