VCC Overshoot Specification
The Celeron D processor in the 775-land package can tolerate short transient overshoot events
where VCC exceeds the VID voltage when transitioning from a high to low current load condition.
This overshoot cannot exceed VID + V
OS
_MAX (VOS_MAX is the maximum allowable overshoot
voltage). The time duration of the overshoot event must not exceed T
OS
_MAX (TOS_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. VOS is measured overshoot voltage.
2. TOS is measured time duration above VID.
2.12.1
Die Voltage Validation
Overshoot events from application testing on real processors must meet the specifications in
Table 2-16 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
should be taken with a 100 MHz bandwidth limited oscilloscope. Refer to the Voltage Regulator
Down (VRD) 10.1 Design Guide For Desktop LGA775 Socket for additional voltage regulator
validation details.
