Overshoot Specification
Processors 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 above
VID). These specifications apply to the processor die voltage as measured across the
VCC_SENSE and VSS_SENSE pins and across the VCC_SENSE2 and VSS_SENSE2 pins.
VCC_SENSE and VSS_SENSE pins and across the VCC_SENSE2 and VSS_SENSE2 pins.
Notes:
1.
VOS is the measured overshoot voltage.
2.
TOS is the measured time duration above VID.

Die Voltage Validation
Core voltage (VCC) overshoot events at the processor must meet the specifications in
when measured across the VCC_SENSE and VSS_SENSE pins and across
the VCC_SENSE2 and VSS_SENSE2 pins. Overshoot events that are < 10 ns in duration
may be ignored. These measurements of processor die level overshoot should be taken
with a 100 MHz bandwidth limited oscilloscope.
