Overshoot/Undershoot Guidelines

Overshoot (or undershoot) is the absolute value of the maximum voltage above VCC or below VSS. The PCH can be damaged by single and/or repeated overshoot or undershoot events on any input, output, or I/O buffer if the charge is large enough. Baseboard designs that meet signal integrity and timing requirements and that do not exceed the maximum overshoot or undershoot limits listed will ensure reliable I/O performance for the lifetime of the PCH.
