CC
Overshoot Specification
The Low Voltage Intel
®
Xeon™ processor with 800 MHz system bus 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 above VID). These specifications apply to the processor die voltage
as measured across the VCCSENSE and VSSSENSE pins.
NOTES:
1. V
OS
is measured overshoot voltage.
2. T
OS
is measured time duration above VID.
