Notes
14. Guaranteed by statistical correlation. Tested initially and after any design or process changes that affects these parameters.
15. Rise and fall times are measured between 2.0V and 0.8V.

17. t
18. UI = unit interval. Examples: 1 UI is a full period. 0.1UI is 10% of period.
19. Measured at 0.5V deviation from starting voltage.
