Figure 26. Parallel data transmission example.
The figure shows data and clock signals at the inputs and
outputs of the optocouplers. To obtain the maximum
data transmission rate, both edges of the clock signal are
being used to clock the data; if only one edge were used,
the clock signal would need to be twice as fast.
Propagation delay skew represents the uncertainty of
where an edge might be after being sent through an op-
tocoupler. Figure 26 shows that there will be uncertainty
in both the data and the clock lines. It is important that
these two areas of uncertainty not overlap, otherwise
the clock signal might arrive before all of the data out-
puts have settled, or some of the data outputs may start

considerations, the absolute minimum pulse width that
can be sent through optocouplers in a parallel applica-
tion is twice t
longer pulse width to ensure that any additional uncer-
tainty in the rest of the circuit does not cause a prob-
lem.
