Withtheincreasingspeedof datatransmission(PC,TV,...),engineersarenaturallyconfrontedwith effects
that were of less significance with slower circuits. Among these are the effects described in transmission
linetheory : line reflectionsprovide signal distortionsand the overshootsor undershootsproducedon the
signaledgescan finallycausethe malfunctionof thewhole system.
1. Reflectionat a nonterminated line
Thefigurebelowshowsthe circuitof atransmissionsystemin whicha memorydevice(inputimpedance of
100k
) is connectedat the endof aline with lineimpedanceZo.
APPLICATIONNOTE: BUSTERMINATION

100 k
If thisline is not properlyterminated, acertainamountof theenergyis reflectedback,inducing a reflection
phenomenathat can distortthe signal.This can resultin improperoperationof the system.
Thesimulation shownon the abovefigure illustratesthe signal distortionproducedby linereflection at the
endof theline whichis not well terminated.
Evenif thesignalat thestartof theline hasthe correctform(upper curve),considerabledistortion arisesat
theend of the line (lower curve).On the positiveedge, the overshootcan exceedthe maximum operating
voltageof the usedcircuittechnologywhichwill thenbedestroyed.Also,thefollowingnegativeundershoot
mayreach a levellow enoughtochangethe valueof thelogicstate.If it affectsof an addressline, a wrong
memorycell will be addressed,and in the caseof a dataline, thedata can be corrupted.
Thisphenomenaalso occurson the fallingedge.
To avoid these negative effects from leading to problems in a system, a suitable termination is
required.
