Overshoot
The 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
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.

Die Voltage Validation
Overshoot events on processor must meet the specifications in
when
measured across the VCC_SENSE and VSS_SENSE lands. Overshoot events that are
< 10 ns in duration may be ignored. These measurements of processor die level
overshoot must be taken with a bandwidth limited oscilloscope set to a greater than or
equal to 100 MHz bandwidth limit.
