Overshoot Specification
The Pentium D processor can tolerate short transient overshoot events where V
CC
exceeds the VID
voltage when transitioning from a high-to-low current load condition. This overshoot cannot
exceed VID + V
OS_MAX
(V
OS_MAX
is the maximum allowable overshoot voltage). The time
duration of the overshoot event must not exceed T
OS_MAX
(T
OS_MAX
is the maximum allowable
time duration above VID). These specifications apply to the processor die voltage as measured
across the VCC_SENSE and VSS_SENSE lands.
NOTES:
1. V
OS
is measured overshoot voltage.
2. T
OS
is measured time duration above VID.
