(1) All typical values are at 25C and with a 3.3-V supply.
(2) Parameters t
P1
and t
P2
are measured from the 1.5 V point of the input to the crossover point of the outputs (see Figure 1 ).
(3) t
skew(pp)
is the magnitude of the difference in differential propagation delay times, t
P1
or t
P2
, between any specified outputs of two devices
when both devices operate with the same supply voltage, at the same temperature, and have identical packages and test circuits.
(4) Δ t
skew
is the magnitude of the difference in differential skew t
skew1
between any specified outputs of a single device.
