                Clock Outputs
| Number | Done? | Checklist Item | 
|---|---|---|
| 1 | Check that the PLL offers the required number of clock outputs and use dedicated clock output pins. | 
You can connect clock outputs to dedicated clock output pins or dedicated clock networks. There is no dedicated clock out pin for fractional PLL. I/O PLL can connect to a clock network or a dedicated clock pin.
