6.1.5 Step 5

Enter desired target frequencies for each of the outputs as well as desired output format, output source, whether the output is SYSREF, and whether the output is being used or not.

Press the Calculate VCO Frequency Options to generate a list of possible VCO frequency combinations.

Select a desired combination of VCO frequencies from the list of calculated values. If a specific VCO frequency is not in this list, a manual override can occur by selecting the Enable User Override check box and typing in the desired VCO frequencies. The Copy to Selected VCO Frequency box can also be used to copy the VCO frequency in the list selections to the VCO overrides.

Press the Assign Selected VCO Settings to Device to update the VCO frequencies. Press the Apply Output Clock Settings to Device button. By default, the analog PLL frequencies are shown; however the DPLL calculated frequency from step 6 will result in exact output frequencies.
