t
SKD1
is the magnitude difference in differential propagation delay time between the positive going edge and the negative going edge of the same channel.

Channel-to-channel skew, t
SKD2
, is the defined as the difference between the propagation delay of one channel and the propagation delay of the other channel on the
same chip with any event on the inputs.
6
t
SKD3
, part-to-part skew, is the differential channel-to-channel skew of any event between devices. This specification applies to devices at the same V
CC
and within 5°C of
each other within the operating temperature range.

t
SKD4
, part-to-part skew, is the differential channel-to-channel skew of any event between devices. This specification applies to devices over recommended operating
temperature and voltage ranges, and across process distribution. t
SKD4
