A. Output skew, tsk(o), is calculated as the greater of:

â The difference between the fastest and slowest of tPLHn (n = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10)

â The difference between the fastest and slowest of tPHLn(n = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10)

B. Pulse skew, tsk(p), is calculated as the greater of | tPLHn - tPHLn | (n = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10).

C. Process skew, tsk(pr), is calculated as the greater of:

â The difference between the fastest and slowest of tPLHn (n = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10) across multiple devices under

identical operating conditions

â The difference between the fastest and slowest of tPHLn (n = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10) across multiple devices under

identical operating conditions
