Figure 13. Propagation delay skew waveform.
Figure 14. Parallel data transmission example.
Propagation delay skew represents the uncertainty of
where an edge might be after being sent through an op-
tocoupler. Figure 14 shows that there will be uncertainty
in both the data and clock lines. It is important that these
two areas of uncertainty not overlap, otherwise the clock
signal might arrive before all of the data outputs have
settled, or some of the data outputs may start to change
before the clock signal has arrived. From these consider-
ations,theabsoluteminimumpulsewidththatcanbesent

Pulse-width distortion (PWD) is the difference between
tPHL and tPLH and often determines the maximum data
rate capability of a transmission system. PWD can be
expressed in percent by dividing the PWD (in ns) by the
minimum pulse width (in ns) being transmitted. Typical-
ly, PWD on the order of 20 - 30% of the minimum pulse
width is tolerable.
Propagation delay skew, tPSK, is an important parameter
to consider in parallel data applications where synchro-
nization of signals on parallel data lines is a concern. If
the parallel data is being sent through a group of opto-
couplers, differences in propagation delays will cause the
data to arrive at the outputs of the optocouplers at differ-
ent times. If this difference in propagation delay is large
enough it will determine the maximum rate at which
parallel data can be sent through the optocouplers.
Propagation delay skew is defined as the difference be-
tween the minimum and maximum propagation delays,
either tPLH or tPHL, for any given group of optocouplers
which are operating under the same conditions (i.e., the
same drive current, supply voltage, output load, and op-
erating temperature). As illustrated in Figure 13, if the in-
puts of a group of optocouplers are switched either ON
or OFF at the same time, tPSK is the difference between
the shortest propagation delay, either tPLH or tPHL, and
the longest propagation delay, either tPLH or tPHL.
As mentioned earlier, tPSK can determine the maximum
parallel data transmission rate. Figure 14 is the timing
diagram of a typical parallel data application with both
the clock and data lines being sent through the opto-
couplers. The figure shows data and clock signals at the
inputs and outputs of the optocouplers. In this case the
data is assumed to be clocked off of the rising edge of
the clock.
A cautious design should use a slightly longer pulse
width to ensure that any additional uncertainty in the
rest of the circuit does not cause a problem.
The HCPL-772X/072X optocouplers offer the advantage
of guaranteed specifications for propagation delays,
pulse-width distortion, and propagation delay skew
over the recommended temperature and power supply
ranges.
