What does an eye diagram tell us?
Simply put, an eye diagram is a data dependent electrical measurement used to evaluate high speed data quality. An eye diagram is measured in the time domain. And as with most time domain electrical measurements, variation in the measurement will occur in every set of samples.
What is an eye diagram in signal integrity?
The data eye diagram is a methodology to represent and analyze a high speed digital signal. The eye diagram allows key parameters of the electrical quality of the signal to be quickly visualized and determined.
