An eye-pattern diagram is a good method for quickly visualizing and accurately measuring timing jitter (see the figure, b). Typical communications applications usually seek a BER of about 1 × 10 -12.

Eye diagram analysis provides a powerful visual tool to assess the quality of high-speed signalling by revealing the cumulative effects of jitter, noise, crosstalk, and other distortions.

It effectively regulates the minimum allowable opening of the eye diagram and prevents excessive overshoot and undershoot, harmful to a receiver.

The eye diagram is captured using a PRBS-like pattern, incorporating a package and system board representative of a typical MRDIMM channel. Using PRBS-like patterns is crucial for capturing accurate ...
