The DAC sampling rate is limited to 7 GSPS because the design is set to Full Bandwidth mode (DUC 0 to Fs/2) in the Datapath options on the DAC Setup tab.
It is possible to select a sampling rate up to 8.92 GSPS by switching the Datapath mode to either Low Pass (DUC 0 to Fs/4), High Pass (DUC Fs/4 to Fs/2), or No DUC mode (0 to Fs/2).
Additionally, please note that the Low Pass and High Pass modes have an effective bandwidth of Fs/2.
Finally, the highest DAC sampling rate achievable for a speed grade -1 device is 8.92 GSPS, whereas a speed grade -2 device can achieve up to 9.7 GSPS.
