Electrical Specifications
3. The voltage specification requirements are measured across VCC_SENSE and VSS_SENSE pins at the
socket with a 100 MHz bandwidth oscilloscope, 1.5 pF maximum probe capacitance, and 1 MΩ minimum im-
pedance. The maximum length of ground wire on the probe should be less than 5 mm. Ensure external noise
from the system is not coupled into the oscilloscope probe.
4.
Refer to Table 2-9 and Figure 2-2 for the minimum, typical, and maximum V allowed for a given current. The
CC
processor should not be subjected to any V and I combination wherein V exceeds V for a giv-

NOTES:
1.
The loadline specification includes both static and transient limits except for overshoot allowed as
shown in Section 2.12.
2.
This table is intended to aid in reading discrete points on Figure 2-3.
3. The loadlines specify voltage limits at the die measured at the VCC_SENSE and VSS_SENSE
pins. Voltage regulation feedback for voltage regulator circuits must be taken from processor VCC
and VSS pins. Refer to the Voltage Regulator-Down (VRD) 10.0 Design Guidelines for Desktop
Socket 478 for socket loadline guidelines and VR implementation details.
