3 Source Eye Diagram Differential Tests
PASS Condition
The following table and figure define the mask for the eye measurements.
There can be no signal trajectories entering into the mask. Table 2 shows
the voltage and time coordinates for the mask used in the eye diagram.
The specification states that either 400mV, 600mV, or 800mV setting must
pass.
