Propagation Delay, Pulse Width Distortion and Propagation Delay Deviation Propagation delay describes how quickly a logic signal propagates through a system. This low-to-high propagation delay (tPLH) is the amount of time it takes for the input signal to propagate to the output for the output to go from low to high. Likewise the propagation delay from high to low (tPHL) is the amount of time it takes for the input signal to propagate to the output to make the output go from high to low (see figure). Pulse Width Distortion (PWD) results for different tPLH and tPHL values. PWD is defined as tPLH and TPHL often determine the maximum data rate capability of the transmission system. PWD can be expressed as a percentage by dividing the PWD (unit: ns) by the minimum pulse width (unit: ns) being transmitted. Generally, a PWD of about the minimum pulse width is acceptable; the exact number depends on the specific application (RS232, RS422, Tl, etc.).
Propagation delay skew (tPSK) is considered a problem for signals on parallel data lines in parallel data applications. If parallel data is sent through a set of optocouplers, the propagation delay will cause the data to arrive at the optocouplers output at different times. If this differential propagation delay is large enough, it will determine the maximum rate at which parallel data can be sent through the optocoupler. Propagation delay deviation is defined as the minimum and maximum propagation delay, TPLH or tPHL, for any set of operating optocouplers under the same conditions (ie, the same drive current, supply voltage, output load, and operating temperature). As shown, if the inputs of a set of optocouplers are turned on or off at the same time, tPSK is the difference between the shortest propagation delay (tPLH), or tPHL, and the longest propagation delay, either tPLH or tPHL. As mentioned earlier, TPSK can determine maximum parallelism. data transfer rate. The picture is with a clock and a data line sent through an optocoupler. The figure shows the input and output data and clock signal optocouplers. For maximum data transfer rates, both edges of the clock signal are used to clock the data; if only one edge is used, the clock signal will need to be twice as fast.
Propagation delay deviation indicates that the edge may be sent through the optocoupler. The graph shows the uncertainty in both the data and the clock line. It is important that these two aspects of uncertainty do not overlap, otherwise the clock signal may arrive before all data outputs have finished, or some data outputs may start changing before the clock signal arrives. From these considerations, the absolute minimum pulse width that can be sent through an optocoupler in parallel applications is twice tPSK. A prudent design should use a slightly longer pulse width to ensure that the rest of the circuit does not cause a malfunction. Optocouplers specified by tPSK offer guaranteed propagation delay specifications, pulse width distortion and propagation delay over recommended values for temperature, input current and power supply range.
