|, 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. Specified 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.
