A recovered Tx UI is calculated over 3500 consecutive unit intervals of sample data. The eye diagram is created using all edges
of the 250 consecutive UI in the center of the 3500 UI used for calculating the Tx UI.
NOTE
It is recommended that the recovered Tx UI be calculated using all edges in the 3500
consecutive UI interval with a fit algorithm using a minimization merit function (that is,
least squares and median deviation fits).
