(1) Data presented in this graph was collected using the DS15BR400EVK, a pair of RJ-45 to SMA adapter boards and various length
Belden 1700a cables. The maximum data rate was determined based on total jitter (0.25 UI criteria) measured after the cable. The total
jitter was a peak to peak value measured with a histogram including 3000 window hits.
