(1) Output transition time measured between 20% to 80% of PAD voltage.
(2) V_HYS is the magnitude of the difference between the positive-going threshold voltage V_T+ and the negative-going threshold voltage V_T–.
(3) Depending on the programming mode, different output load and transition time are available following the targeted maximum frequency,
transmission line or output transition time.
