NOTES: A. Output skew, tsk(o), is calculated as the greater of:
The difference between the fastest and the slowest tpd(LH)n (n = 0…2)
The difference between the fastest and the slowest tpd(HL)n (n = 0…2)
B. Part-to-part skew, tsk(pp), is calculated as the greater of:
The difference between the fastest and the slowest tpd(LH)n (n = 0…2 for LVPECL, n = 3 for LVCMOS) across multiple devices
The difference between the fastest and the slowest tpd(HL)n (n = 0…2 for LVPECL, n = 3 for LVCMOS) across multiple devices
C. Pulse skew, tsk(p), is calculated as the magnitude of the absolute time difference between the high-to-low (tpd(HL) and the low-to-high
(tpd(LH)) propagation delays when a single switching input causes one or more outputs to switch, tsk(p) = | tpd(HL) tpd(LH) |. Pulse skew
is sometimes referred to as pulse width distortion or duty cycle skew.
