• At the Beginning of Life (BOL)
• Over the specified operating temperature and voltage ranges
• Input is at 622.08 Mbd, 2
• Receiver worst-case output data eye-opening (window time-width) is measured by applying worst-case input systematic (SJ) and random
• Input optical rise and fall times (10% - 90%) are 0.7 ns and 0.9 ns respectively.
• Transmitter operating with a 622.08 MBd, 311.04 MHz square wave input signal to simulate any cross talk present between the transmitter
jitter (RJ). The worst-case maximum input SJ = 0.5 ns peak-to-peak and the RJ = 0.15 ns peak-to-peak per ANSI T1.646a standard. Since
the input (transmitter) random jitter contribution is very small and difficult to produce exactly, only the maximum systematic jitter is
produced and used for testing the receiver. The corresponding receiver test window time-width must meet the requirement of 0.31 ns or
larger. This worst-case test window time-width results from the following jitter equation:
Minimum Test Window Time-Width = Baud Interval - Tx SJ max. - Rx SJ max. - Rx RJ max.
Respectively, Minimum Test Window Time-Width = 1.608 ns - 0.50 ns - 0.30 ns - 0.48 ns = 0.328 ns.
This is a test method that is within practical test error of the worst-case 0.31 ns limit.
