A. Output skew, tsk(o), is calculated as the greater of:
⢠The difference between the fastest and slowest of tphase error n (n = 1, 2, . . . 6)
⢠The difference between the fastest and slowest of tphase error n (n = 7, 8, 9)
B. Process skew, tsk(pr), is calculated as the greater of:
⢠The difference between the maximum and minimum tphase error n (n = 1, 2, . . . 6) across multiple devices under
identical operating conditions.
⢠The difference between the maximum and minimum tphase error n (n = 7, 8, 9) across multiple devices under
identical operating conditions.
