(1) Output transition time measured between 20% to 80% of PAD voltage.
(2) In vdds_dv_y, y can have the value: bank3 or bank5 depending on the ball used. For more information on a ball and the corresponding
power, see Table 2-1, POWER [9] column.
(3) V_HYS is the magnitude of the difference between the positive-going threshold voltage V_T+ and the negative-going threshold voltage V_T–.
(4) Depending on the programming mode, different output load and transition time are available following the targeted maximum frequency,
transmission line or output transition time.
