Notes:
6. Parameters are guaranteed by design and characterization. Not 100% tested in production. All parameters specified with loaded outputs.
7. Outputs driving 50Ω transmission lines.
8. 50% input duty cycle.
9. Outputs loaded with 30 pF each.
10. Part-to-Part Skew at a given temperature and voltage.
11. Set-up and Hold times are relative to the falling edge of the input clock.
