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

– The difference between the fastest and slowest of tPLHn (n = 1:10)

– The difference between the fastest and slowest of tPHLn (n = 1:10)

B. Pulse skew, tsk(p), is calculated as the greater of |tPLHn – tPHLn| (n = 1:10).

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

– The difference between the fastest and slowest of tPLHn (n = 1:10) across multiple devices under identical operating conditions

– The difference between the fastest and slowest of tPHLn (n = 1:10) across multiple devices under identical operating conditions
