Tool/software:
Query 1:
We are using DAC39RF10EVM, In datasheet it is mentioned that the maximum input data rate is 20.48 GSPS in single channel mode. But in the DAC39RF10EVM GUI we can't able to setup the clock frequency above 12GHz. Please let us know which is limiting the maximum clock frequency. If it is possible to feed clock externally above 12GHz explain the procedure to sweep 7.75GHz to 12.5GHz using 14GHz clock frequency.
Query 2:
We are using DAC39RF10EVM, Our requirement is to generate DAC output frequency from 7.75GHz to 12.5GHz using 6.5GHz external clock. From the datasheet we noted that in DES2XH mode the Fout/Fclk vs output power graph showing power levels in 3rd nyquist zone . But in the DAC39RF10EVM GUI we can't able to setup the DAC output frequency greater than clock frequency. Please let us know the procedure which meets our requirement.
