Propagation Delay, Pulse-Width Distortion and Propagation Delay Skew
Propagation delay is a figure of merit which describeshow quickly a logic signal propagates through a sys-tem.Thepropagationdelayfromlowtohigh(tPLH)istheamountoftimerequiredforaninputsignaltopropagatetotheoutput,causingtheoutputtochangefromlowtohigh.Similarly, thepropagationdelay fromhighto low(tPHL)istheamountoftimerequiredfortheinputsignaltopropagatetotheoutputcausingtheoutputtochangefromhightolow(seeFigure8).
Pulse-width distortion (PWD) results when tPLH and tPHLdiffer in value. PWD is defined as the difference be-tweentPLHandtPHLandoftendeterminesthemaximumdata rate capabilityofa transmissionsystem.PWDcanbeexpressedinpercentbydividingthePWD(inns)bytheminimumpulsewidth(inns)beingtransmitted.Typi-cally,PWDontheorderof20-30%oftheminimumpulsewidthistolerable;theexactfiguredependsonthepar-ticularapplication(RS232,RS422,T-l,etc.).

As mentioned earlier, tPSK can determine the maximumparallel data transmission rate. Figure 20 is the timingdiagramofatypicalparalleldataapplicationwithboththe clock and the data lines being sent through opto-couplers.Thefigureshowsdataandclocksignalsattheinputs and outputs of the optocouplers.To obtain themaximum data transmission rate, both edges of theclocksignalarebeingusedtoclockthedata;ifonlyoneedgewereused,theclocksignalwouldneedtobetwiceasfast.
Propagation delay skew represents the uncertainty ofwhere an edge might be after being sent through anoptocoupler. Figure 20 shows that there will be uncer-taintyinboththedataandtheclocklines.Itisimportantthat these two areas of uncertainty not overlap, other-wisetheclocksignalmightarrivebeforeallofthedataoutputshavesettled,orsomeofthedataoutputsmaystarttochangebeforetheclocksignalhasarrived.Fromtheseconsiderations,theabsoluteminimumpulsewidththatcanbesentthroughoptocouplersinaparallelappli-cationistwicetPSK.Acautiousdesignshoulduseaslightlylongerpulsewidthtoensurethatanyadditionaluncer-taintyintherestofthecircuitdoesnotcauseaproblem.
