Propagation Delay, Pulse-Width Distortion and Propa-
gation Delay Skew
Propagation delay is a figure of merit which describes
how quickly a logic signal propagates through a sys-
tem. The propagation delay from low to high (t
amount of time required for an input signal to propa-
gate to the output, causing the output to change from
low to high. Similarly, the propagation delay from high
to low (t
signal to propagate to the output, causing the output to
change from high to low (see Figure 9).
Pulse-width distortion (PWD) results when t
differ in value. PWD is defined as the difference between
t
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. Typi-
cally, PWD on the order of 20-30% of the minimum pulse
width is tolerable; the exact figure depends on the par-
ticular application (RS232, RS422, T-1, etc.).

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
different 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 optocou-
plers.
Propagation delay skew is defined as the difference be-
tween the minimum and maximum propagation delays,
either t
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 25, if the in-
puts of a group of optocouplers are switched either ON

diagram of a typical parallel data application with both
the clock and the data lines being sent through opto-
couplers.
