EVALUATING THE AD9152 DIGITAL-TO-ANALOG CONVERTER
This user guide describes both the hardware and software setup needed to acquire data capture from AD9152-FMC-EBZ evaluation board to characterize AD9152 16-bit 2.25Gsps dual JESD204B signal processing RF Digital to Analog Converter.
The AD9152-FMC-EBZ is an FMC mezzanine card and connects to an ADS7-V2 or ADS8-V1 data pattern generator system. The ADS7-V2/ADS8-V1 automatically formats the data and sends it to the AD9152-FMC-EBZ via its JESD204B lanes. +12V, +3.3V, and VADJ power supply rails are provided by the ADS7-V2/ADS8-V1 system via the FMC connector P1. A clock distribution chip AD9516 is included on this EVB as a clock fan-out and frequency divider for the DACCLK, JESD204B SYSREF signals, and a GBTCLK clock used by the ADS7-V2/ADS8-V1. There is also an FMC standard I2C bus that is used by the ADS7-V2/ADS8-V1 to identify the AD9152-FMC-EBZ. This I2C interface is implemented in software in the AD9152-FMC-EBZ PIC processor (XU1). All ADS7-V2/ADS8-V1 to/from AD9152-FMC-EBZ interface signals are connected via the FMC connector P1.

Quick Start Guide
Attach AD9152-FMC-EBZ onto the FMC connector of ADS7-V2 or ADS8-V1 controller board. Connect the evaluation board to PC via USB
, the continuous waveform generator output to J1, and one of the DAC outputs (J4 or J17) to a signal/spectrum analyzer. Connect ADS7-V2/ADS8-V1 to PC via USB
and to a 12V 60W AC/DC power supply, then switch the board ON using S1 beside the connector for 12V supply. Refer to Typical Setup
section for pictures of actual evaluation setup.
Set the frequency of the continuous waveform generator output to 1.5 GHz
and the output level to +3 dBm
. Enable the output.
Figure 2. ADS7-V2 and AD9152 detected in DPG Software
Start DPG Lite or DPG Downloader. A panel named after the detected controller board should appear at the bottom of the DPG window. The device on the evaluation board and the data interface should also be automatically detected by the software and shown at Evaluation Board
and Port Configuration
, respectively. See Figure 2.
Figure 3. AD9152-FMC-EBZ detected in ACE
Open ACE. The board will automatically be recognized by the software as shown in Figure 3. Otherwise, install the plugin for AD9152 evaluation board by following the steps in this page: Quickstart - ACE Quickstart and Plug-in Installation

In DPG Lite or DPG Downloader, configure single tone waveform generation. From the Add Generator Waveforms pulldown menu, select Single Tone. Apply the following settings:
In the ADS7-V2 or ADS8-V1 panel in the DPG window, configure Data Playback
by selecting tones for the DAC outputs from each dropdown menu. Set JESD Mode
to Mode 4, Links
to Single and Subclass

Press the download arrow (
) then the play button (
). As in Figure 6, Serial Line Rate
should appear as 3.75 Gbps
and Sync Status
should have a check mark. FFT plot of the DAC output is in Figure 7.
