NOTES:
1.
The loadline specification includes both static and transient limits except for overshoot allowed as shown in
2.
This loadline specification shows the deviation from the VID set point.
3.
The loadlines specify voltage limits at the die measured at the VCC_SENSE and VSS_SENSE lands. Voltage
regulation feedback for voltage regulator circuits must be taken from processor VCC and VSS lands. Refer
to the Voltage Regulator Design Guide for socket loadline guidelines and VR implementation details.
2.6.3
V
CC
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
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.
