APPLICATION NOTE
Creating Eye Displays Using Probe
In communications work, the eye display is frequently used to illustrate the voltage and timing margins present in
a system transmitting digital data. In an eye display the signal is shown with a time axis that is a small number of
data periods long. The signal wraps from the right edge of the display back to the left edge, thereby depicting a
large number of overlapping data periods. If a random bit pattern is simulated and then displayed in this way, the
required margins can be seen as the opening in the eye on the display.
