A. NOTES: . Output skew, tsk(o), is calculated as the greater of:
The difference between the fastest and slowest of tphase error n (n = 10, 11, . . . 15)
B. Process skew, tsk(pr), is calculated as the greater of:
•
•
The difference between the maximum and minimum tphase
under identical operating conditions.
