No test load is necessarily associated with this value.
Specified at the measurement point into a timing and voltage compliance test load and measured over any 250 consecutive
TX UIs.
No test load is necessarily associated with this value.
Specified at the measurement point and measured over any 250 consecutive UIs. If the clock to the RX and TX are not
derived from the same reference clock, the TX UI recovered from 3500 consecutive UI must be used as a reference for the
eye diagram.
A TRX-EYE=0.40UI provides for a total sum of 0.60 UI deterministic and random jitter budget for the Transmitter and
interconnect collected any 250 consecutive UIs. The TRX-EYE-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.6 UI 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. If the clocks to the RX and TX are not derived from the same reference clock, the TX UI recovered from 3500
consecutive UI must be used as the reference for the eye diagram.
The Receiver input impedance shall result in a differential return loss greater than or equal to 15 dB with the D+ line biased to
300mV and the D- line biased to -300 mV and a common mode return loss greater than or equal to 6 dB (no bias required)
over a frequency range of 50 MHz to 1.25 GHz. This input impedance requirement applies to all valid input levels. The
reference impedance for return loss measurements for is 50 ohms to ground for both the D+ and D- line (that is, as measured
by a Vector Network Analyzer with 50 ohm probes). Note: that the series capacitors CTX is optional for the return loss
measurement.
