(1) All typicals are given for V_CC = 3.3V and T_A = 25°C.
(2) C_L includes fixture capacitance and C_D includes probe capacitance.
(3) t_SKD1, |t_PLHD − t_PHLD|, is the magnitude difference in differential propagation delay time between the positive going edge and the negative
going edge of the same channel.
(4) Not production tested. Guaranteed by a statistical analysis on a sample basis at the time of characterization.
(5) t_SKD3, Part-to-Part Skew, is defined as the difference between the minimum and maximum specified differential propagation delays. This
specification applies to devices at the same V_CC and within 5°C of each other within the operating temperature range.
(6) Stimulus and fixture Jitter has been subtracted.
