Introduction
The AD9136/AD9135-EBZ connects to a DPG3 for quick evaluation of the AD9136/AD9135, a
high-speed, signal processing Digital to Analog Converter. The DPG3 automatically formats the data
and sends it to the AD9136/AD9135-EBZ, simplifying evaluation of the device. The Evaluation Board
(EVB) runs from a +5V supply. A clock distribution chip AD9516 is included on this EVB as a clock
fan-out and frequency divider for the DACCLK, REFCLK and DPG3 input clock. Figure 2 is an image of
the top side of the AD9136-EBZ.
AD9136/AD9135 Evaluation Software
The AD9136/AD9135 Evaluation Board software has an easy-to-use graphical user interface (GUI). It is

included on the Evaluation Board CD, or can be downloaded from the DPG website at
http://www.analog.com/dpg. This will install DPGDownloader (for generating and loading vectors into
the DPG3) and AD9136/AD9135 SPI software.
Hardware Setup
Connect +5.0V to P5, GND to P6. A low phase noise high frequency clock source should be connected
to the SMA connector, J1. This is the DACCLK input. The spectrum analyzer should be connected to
the SMA connector, J17. This is the DAC0 output. The evaluation board connects to the DPG3 through
the connector P4. The PC should be connected to the EVB using the mini-USB connector XP2 after
installation of the Evaluation Board software. Figure 1 shows the block diagram of the set-up.

Getting Started
The PC software comes on the included Evaluation Board CD, but may also be downloaded from the
DPG Web site at http://www.analog.com/dpg. The installation will include the DPG Downloader
software as well as all the necessary AD9136/AD9135 files including schematic, board layout,
datasheet, AD9136/AD9135 SPI, and other files.
Initial Set-Up
1. Install the DPG Downloader and AD9136/AD9135 SPI software and support files on your PC. Follow
the instructions in the installation wizard and use the default (recommended) installation settings.
2. Use a USB cable to connect the EVB to your PC and connect the lab equipment to the EVB.
3. Connect the DGP3 unit to your PC and turn on the unit.

Single-Tone Test
These settings configure the AD9136/AD9135 to output a sine wave using the DPG3 and allow the
user to view the single-tone performance at the DAC output, under the condition: Fdata = 1.6GHz, 1X
interpolation, 4-carrier WCDMA signal with center frequency = 100MHz.
Configure DPG Vector Software
1. To begin, turn on the external +5V supply.
2. Open DPG Downloader if you have not done so. (Start > All Programs > Analog Devices > DPG >
DPGDownloader). Ensure that the program detects the AD9136/AD9135, as indicated in the
“Evaluation Board” drop-down list, and select it. Select “QBF 2×4 85G 425M” from the “Port
Configuration” drop-down list and “Mode 8” from the “JESD Mode” drop-down list.
3. Click on “Add Generated Waveform”, and then “Wireless Infrastructure”. A WIFR panel will be
added to the vector list. Enter the Data Rate, in this case 1.6GHz and the desired frequency, 100MHz.
Enter the digital amplitude. In this case we use 0dBFS. Select “2's Complement” from the Number
Format drop-down list. Input the center frequency of “100MHz” at the bottom of the panel, choose
“WCDMA” from the Standard drop-down menu and increase the No. of Carriers to “4” - then hit the
“Add Carriers” button. The DPG Downloader panel should look like Figure 3.
4. Select the WIFR vector (I) in the “DAC0” drop down menu and the WIFR vector (Q) in the “DAC1”.
At this point, the DPG Downloader panel should look like Figure 3.

2. Configure the hardware according to the hardware set-up instructions given in the Hardware Setup
section above. Set the frequency of the DAC clock signal generator to 1.6GHz, and the output level to
3dBm. The spectrum analyzer can be configured with Start Frequency = 1 MHz, Stop Frequency =
800 MHz, and Resolution Bandwidth of 30 kHz, and Trace Detector to Average (Log/RMS/V). Choose
Input Attenuation to be 8dB. This can be adjusted later if indications are that the analyzer is causing
degradations.
3. Follow the sequence below to configure the AD9136/AD9135 SPI registers.
a. The Links should be set to dual link. The JESD Mode is set to 8, Subclass 1 box checked,
Interpolation set to 1, and FDAC set to 1.6GHz. Click “Commit” button to initialize the AD9136/AD9135.
The JESD204B PLL should be locked indicated with bright green JESD204B PLL readback LED.
b. At this point the Serial Line Rate in the DPG3 software panel should read 8Gbps.

e. The current on the 5V supply should read about 1430mA. If you do not see the output, gently push
the board toward the DPG3. This ensures that the board is firmly connected to the DPG3. The four
registers codeGrpSync, FrameSync, GoodCheckSum and Initial LaneSync should all read 0F indicating
the lanes are working correctly.
3. The output spectrum of the DAC should look like Figure 6 below.
