NOTES: A. Output skew, tsk(o), is calculated as the greater of:
– The difference between the fastest and slowest of tPLHn (n = 1:18)
– The difference between the fastest and slowest of tPHLn (n = 1:18)
B. Pulse skew, tsk(p), is calculated as the greater of |tPLHn – tPHLn| (n = 1:18)
C. Process skew, tsk(pr), is calculated as the greater of:
– The difference between the fastest and slowest of tPLHn (n = 1:18) across multiple devices under identical operating conditions
– The difference between the fastest and slowest of tPHLn (n = 1:18) across multiple devices under identical operating conditions
