(3) t
SKD2
, Channel-to-Channel Skew, is defined as the difference between the propagation delay of one channel and that of the others on
the same chip with any event on the inputs.
(4) 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.
(5) 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
(6) 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
is defined as |Max − Min|
differential propagation delay.
