Electrical Characteristics
NOTES:
1. Specified at the measurement point into a timing and voltage compliance test load and
measured over any 250 consecutive TX UIs. (Also refer to the Transmitter compliance eye
diagram)
2. A T

= 0.70 UI provides for a total sum of deterministic and random jitter budget of
T
TXJITTER-MAX
= 0.30 UI for the Transmitter collected over any 250 consecutive TX UIs. The
T
TXEYE-MEDIAN-to-MAX-JITTER
specification ensures a jitter distribution in which the median
and the maximum deviation from the median is less than half of the total TX jitter budget
collected over any 250 consecutive TX UIs. It should be noted that the median is not the
same as the mean. The jitter median describes the point in time where the number of jitter
points on either side is approximately equal as opposed to the averaged time value.
