13 propagation delay, pulse- width distortion and propagation delay skew propagation delay is a figure of merit which describes how quickly a logic signal propagates through a system. the propaga- tion delay from low to high (t plh ) is the amount of time required for an input signal to propagate to the output, causing the output to change from low to high. similarly, the propagation delay from high to low (t phl ) is the amount of time required for the input signal to propagate to the output, causing the output to change from high to low (see figure 5). pulse-width distortion (pwd) results when t plh and t phl differ in value. pwd is defined as the difference between t plh and t phl 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. typically, pwd on the order of 20-30% of the minimum pulse width is tolerable; the exact figure depends on the particular application (rs232, rs422, t-1, etc.). propagation delay skew, t psk , is an important parameter to consider in parallel data applica- tions where synchronization of signals on parallel data lines is a concern. if the parallel data is being sent through a group of optocouplers, differences in propagation delays will cause the data to arrive at the outputs of the optocouplers at different times. if this difference in propagation delays 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 between the minimum and maximum propaga- tion delays, either t plh or t phl , for any given group of optocouplers which are operating under the same conditions (i.e., the same drive current, supply voltage, output load, and operating tem- perature). as illustrated in figure 15, if the inputs of a group of optocouplers are switched either on or off at the same time, t psk is the difference between the shortest propagation delay, either t plh or t phl , and the longest propagation delay, either t plh or t phl . as mentioned earlier, t psk can determine the maximum parallel data transmission rate. figure 16 is the timing diagram of a typical parallel data application with both the clock and the data lines being sent through optocouplers. 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 signals 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 repre- sents the uncertainty of where an edge might be after being sent through an optocoupler. figure 16 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 outputs have settled, or some of the data outputs may start to change before the clock signal has arrived. from these considerations, the absolute minimum pulse width that can be sent through optocouplers in a parallel application is twice t phz . 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-2400/30 optocouplers offer the advantages of guaran- teed specifications for propaga- tion delays, pulse-width distortion, and propagation delay skew over the recommended temperature, input current, and power supply ranges. application circuit a recommended led drive circuit is shown in figure 13. this circuit utilizes several techniques to minimize the total pulse-width distortion at the output of the optocoupler. by using two inverting ttl gates connected in series, the inherent pulse-width distortion of each gate cancels the distortion of the other gate. for best results, the two series- connected gates should be from the same package. the circuit in figure 13 also uses techniques known as prebias and peaking to enhance the performance of the optocoupler led. prebias is a small forward voltage applied to the led when the led is off. this small prebias voltage partially charges the junction capacitance of the led, allowing the led to turn on more quickly. the speed of the led is further increased by applying
