Notes
5. Skew value guaranteed when outputs are generated from the same divider bank.
6. Jitter measurement may vary. Actual jitter is dependent on input jitter and edge rate, number of active outputs, input and output frequencies, supply voltage,
temperature, and output load. For more information, refer to the application note,
