Transmitter Compliance Eye Diagrams
The TX eye diagram in Figure 49 is specified using the passive compliance/test measurement load (see
Figure 51) in place of any real PCI Express interconnect + RX component. There are two eye diagrams
that must be met for the transmitter. Both diagrams must be aligned in time using the jitter median to locate
the center of the eye diagram. The different eye diagrams differ in voltage depending on whether it is a
transition bit or a de-emphasized bit. The exact reduced voltage level of the de-emphasized bit is always
relative to the transition bit.
The eye diagram must be valid for any 250 consecutive UIs.
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).
