PARAMETER MEASUREMENT INFORMATION

CDCLVD110

SCAS684C – SEPTEMBER 2002 – REVISED JANUARY 2008

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)

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

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.
