Notes: 

3. Guaranteed by design, not 100% tested.
4. Guaranteed to meet 20%–80% output thresholds and duty cycle specifications.
5. Reference Output duty cycle depends on XTALIN duty cycle.
6. Jitter varies significantly with configuration. Reference Output jitter depends on XTALIN jitter and edge rate.
