The AD9106-ARDZ-EBZ and AD9102-ARDZ-EBZ evaluation boards share the same PCB design, are compatible with ARM-based Mbed-enabled boards like SDP-K1 and are designed to connect to Arduino Uno headers. Both boards can be operated using either the Example Mbed Program or the Analysis Control Evaluation (ACE) Software. Links to the user guides are provided.
The AD910x-ARDZ-EBZ evaluation setup can be powered by USB only and does not require a high-frequency waveform generator for clock input. The evaluation board has an on-board 156.25 MHz crystal oscillator. To fit the evaluation system in a small form factor and manage power consumption within USB specifications, AD9106 and AD9102 supply voltages AVDD, DVDD and CLKVDD are limited to 3.3V only.
Included also in this page are resources and documentation for the obsolete AD9106-EBZ and AD9102-EBZ boards. These are standalone boards with the same PCB design and are controlled using a Labview-based GUI.
The evaluation board has a provision for on-board or external clocking configuration.

The evaluation board has a provision to connect the DAC Outputs to the RF Balun Transformer or an 0n-board ADA4817-2 Amplifiers.

To properly observe the other patterns out of the amplifiers, replace C25, C26, C54, and C55 with 0Ω resistors or remove the capacitors then solder each pair of pads together. Waveforms are shown in Figures 17a to 18c.
The common-mode voltage of the amplifier outputs can also be changed by installing resistors for DC offset correction of amplifier inputs. Refer to Table 1. Keep C25, C26, C54, and C55 pads shorted.
The on-board amplifiers can be characterized using off-board power supplies by removing E1 and E2 then connecting 5.2V 0.2A across TP5 and ground and -5.2V 0.2A across TP4 and ground. Refer to Table 2.
