NOTES: A. Output skew, t
sk(o),
is calculated as the greater of:
– The difference between the fastest and slowest of t
PLHn
(n = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
– The difference between the fastest and slowest of t
PHLn
(n = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10)
B. Pulse skew, t
sk(p)
, is calculated as the greater of | t
PLH
n – t
PHLn
| (n = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10).
C. Process skew, t
sk(pr)
, is calculated as the greater of:
– The difference between the fastest and slowest of t
PLHn
(n = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10) across multiple devices under identical operating conditions
– The difference between the fastest and slowest of t
PHLn
(n = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10) across multiple devices under identical operating conditions
