Electrical Specifications

Dual-Core Intel® Xeon® Processor 3000 Series Datasheet

Notes:

The loadline specification includes both static and transient limits except for overshoot allowed as shown in

Section 2.6.3.

This loadline specification shows the deviation from the VID set point.

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-Down (VRD) 11.0 Processor Power Delivery Design Guidelines For Desktop

LGA775 Socket for socket loadline guidelines and VR implementation details.
