Maximum Acceptable Overshoot/Undershoot Waveform; Processor Sideband Signal Group Overshoot/Undershoot Tolerance - Intel Xeon Processor E5-1600 Datasheet

the overshoot specification, when you add the total impact of all overshoot events, the
system may fail. A guideline to ensure a system passes the overshoot and undershoot
specifications is shown below.
1. If only one overshoot/undershoot event magnitude occurs, ensure it meets the
over/undershoot specifications in the following tables, OR
2. If multiple overshoots and/or multiple undershoots occur, measure the worst case
pulse duration for each magnitude and compare the results against the AF = 0.1
specifications. If all of these worst case overshoot or undershoot events meet the
specifications (measured time < specifications) in the table (where AF= 0.1), then
the system passes.
