A. NOTES: . Output skew, t_sk(o), is calculated as the greater of:
• The difference between the fastest and slowest of t_{phase error n} (n = 10, 11, . . . 15)
B. Process skew, t_sk(pr), is calculated as the greater of:
• The difference between the maximum and minimum t_{phase error n} (n = 10, 11, . . . 15) across multiple devices
under identical operating conditions.
