CC
Overshoot Specification
The Pentium 4 processor Extreme Edition in the 775-land package 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
where: V
OS_MAX
is the
maximum allowable overshoot voltage. The time duration of the overshoot event must not exceed
T
OS_MAX
where: 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.
Consult Voltage Regulator-Down (VRD) 10.1 Design Guide for Desktop and Transportable Socket
775 for proper application of the overshoot specification.

NOTES:
1. VTTPWRGD is not a feature of the Pentium 4 processor Extreme Edition in the 775-land package. This pin is used by
compatible processors. This pin is required for compatibility with Voltage Regulator Down (VRD) 10.1 Design
Guide standards.
