Electrical Specifications
Table 6.
8.
V_TT must be provided via a separate voltage source and not be connected to V_CC. This
specification is measured at the land.
9.
Baseboard bandwidth is limited to 20 MHz.
10. This is maximum total current drawn from V_TT plane by only the processor. This
specification does not include the current coming from R_TT (through the signal line). Refer
to the Voltage Regulator-Down (VRD) 11.0 Processor Power Delivery Design Guidelines For
Desktop LGA775 Socket to determine the total I_TT drawn by the system. This parameter is
based on design characterization and is not tested.
11. This is maximum total current drawn from V_TT plane by only the processor. This
specification does not include the current coming from R_TT (through the signal line). Refer
to the Voltage Regulator-Down (VRD) 11 Design Guide For Desktop and Transportable
LGA775 to determine the total I_TT drawn by the system. This parameter is based on design
characterization and is not tested.
12. Adherence to the voltage specifications for the processor are required to ensure reliable
processor operation.

NOTES:
1.
The loadline specification includes both static and transient limits except for overshoot
allowed as shown in Section 2.6.3.
2.
This table is intended to aid in reading discrete points on Figure 1.
3.
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 Design
Guide For Desktop and Transportable LGA775 for socket loadline guidelines and VR
implementation details.
4.
Adherence to this loadline specification is required to ensure reliable processor operation.
