Figure The propaga? Similarly, the propagation delay from high to low tPHL 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? PWD can be expressed in percent by dividing the PWD in ns by the minimum pulse width in ns being transmitted. Propagation delay skew, tPSK, is an important parameter to consider in parallel data appli?
If the parallel data is being sent through a group of optocouplers, differ? 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 propagation delays, either tPLH or tPHL, for any given group of optocouplers which are operating under the same conditions i.
As mentioned earlier, tPSK can determine the maximum parallel data transmission rate. Figure 20 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 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 repres? Figure 20 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 considera? 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 tPSK specified optocouplers offer the advantages of guaranteed specifications for propagation delays, pulsewidth distortion and propagation delay skew over the recom? Data subject to change. All rights reserved.
