FMC. See Figure 6 for all jumper connections.
2. Ensure that the data capture board is switched to “OFF.” ( S1 on the data capture board) Connect the evaluation board to the data
capture board via the FMC connector found on the underside of the board, as shown in Figure 1. Connect the power supply and USB
cable to the data capture board.
3. Turn on the ADS7-V2EBZ.
4. The ADS7-V2EBZ should appear in the Device Manager as shown in Figure 7.

5. If the Device Manager does not show the ADS7-V2EBZ listed as shown in Figure 7, unplug all USB devices from the PC, uninstall and
re-install ACE and restart the hardware setup from step 1.
6. On the AD6688 evaluation board, provide a clean, low jitter 3 GHz clock source to connector J201 (preferably via a shielded RG-58 50
Ω coaxial cable) and set the amplitude to 10 dBm. This is the ADC Sample Clock.
7. On the ADS7-V2, provide a clean, low jitter clock source to connector J3 and set the amplitude to 10 dBm. This is the Reference Clock
for the gigabit transceivers in the FPGA. The REFCLK frequency can be calculated using the following empirical formulae:
bps/lane, where
8. On the AD6688 evaluation board, connect a clean signal generator with low phase noise to J101 or J104 via coaxial cable for channels
A and B respectively. It is recommended to use a narrow-band, band-pass filter with 50 Ω terminations and an appropriate center
frequency.
ACE Setup
1. Download and install ACE if it is not already installed.
2. The AD6688 ACE plug-in can be found under the 6688 Evaluation Board Software Section or through ACE's Plug-In Manager (Tools
→ Manage Plug-Ins).
Tip: Some browsers (Such as Internet Explorer) may save the file as a .zip file
instead of an .acezip file. If this happens, simply download and rename the file
with an .acezip file extension.
3. Once the .acezip file has been downloaded from the Analog Devices website, right click on it and install the plug-in, or double click to
install.
4. Click Start → All Programs → Analog Devices → ACE → ACE
5. The AD6688 plug-in should appear as in Figure 8 if successfully installed.
6. If the AD6688 plug-in does not appear, or no board is detected, make sure the ADS7-V2 is powered on and the evaluation board is
properly connected. Make sure that ACE has been updated to the most recent version and the necessary plug-ins have been installed.
