B. Process skew, tsk(pr), is calculated as the greater of:

– The difference between the fastest and slowest tPLHn (n = 1, 2, ...9)

– The difference between the fastest and slowest tPHLn (n = 1, 2, . . . 9) across multiple devices

C. For additional information on skew and propagation delay parameters, see the Defining Skew, Propagation Delay, Phase-Offset

(Phase Error) application note, literature number SCAA055.
