Figure 6-3. Step 3: DPLL Clock Input Selection

6.1.4 Step 4

Step 4 is currently not implemented for 0-Delay setup.

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.

Figure 6-4. Step 5: Clock Outputs

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.
