NOTES: A. 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 error n (n = 10, 11, . . . 15) across multiple devices under identical

operating conditions
