AD9166 : wide instantaneous bandwidth signal and fdac rate

Hello,

Is it able to generate the desired signal on the following conditions?
Our customer wants to generate a 2GHz iBW signal centered on 5GHz using AD9166.
Datarate will be needed 2.5GSPS in complex mode to ensure 2GHz iBW.
It will use 2x interpolation and FIR85 mode and the fdac will be 10GSPS.

In this case, the spectrum is on both sides of the Nyquist frequency of fdac.
I think it will not be able to generate the signal correctly on this condition.
Could you please give me your suggestion?

Best regards,
