a. VUS (Voltage UnderShoot) - Values of Vpeak (peak undershoot voltage) for the maximum Pulse Width
specified.
b. VOS (Voltage OverShoot) - Values of Vpeak (peak overshoot voltage) for the maximum Pulse Width specified.
c. PW (Pulse Width) - Maximum Pulse Width allowed for a given Vpeak value (undershoot or overshoot), such
that the reliability specifications of the device are not exceeded.
d. Values provided in this table apply to Input and I/O pins in the GbE signal group. For more details, follow the
table link provided.
