7 Parameter Measurement Information

CDCLVD110A pmi_wf_cas684.gif
A. Output skew, tsk(o), is calculated as the greater of:
– The difference between the fastest and the slowest tPLHn (n = 1, 2,...10)
– The difference between the fastest and the slowest tPHLn (n = 1, 2,...10)
B. Part-to-part skew, tsk(pp), is calculated as the greater of:
– The difference between the fastest and the slowest tPLHn (n = 1, 2,...10) across multiple devices
– The difference between the fastest and the slowest tPHLn (n = 1, 2,...10) across multiple devices
C. Pulse skew, tsk(p), is calculated as the magnitude of the absolute time difference between the high-to-low (tPHL) and the low-to-high (tPLH) propagation delays when a single switching input causes one or more outputs to switch,
tsk(p) = | tPHL – tPLH |. Pulse skew is sometimes referred to as pulse-width distortion or duty-cycle skew.
