Electrical Specifications
2.
These voltages are targets only. A variable voltage source should exist on systems in the event that a different voltage is re-
quired. See Section 2.4 and Table 2-2 for more information.
3.
The voltage specification requirements are measured across VCC_SENSE and VSS_SENSE lands at the socket with a
100 MHz bandwidth oscilloscope, 1.5 pF maximum probe capacitance, and 1 M
Ω minimum impedance. 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 oscillo-
scope probe.
4.
775_VR_CONFIG_04A refers to voltage regulator configurations that are defined in the Voltage Regulator Down (VRD) 10.1
Design Guide For Desktop LGA775 Socket.
5.
Refer to Table 2-9 and Figure 2-2 for the minimum, typical, and maximum VCC allowed for a given current. The processor
should not be subjected to any VCC and ICC combination wherein VCC exceeds VCC_max for a given current.
6.
These frequencies will operate properly in a system designed for 775_VR_CONFIG_04B processors. The power and ICC will
be incrementally higher in this configuration due to the improved loadline and resulting higher VCC.
7.
ICC_max is specified at VCC_max.
8.
The current specified is also for AutoHALT State.
9.
Icc Stop-Grant and ICC Sleep are specified at VCC_max.
10.
The maximum instantaneous current the processor will draw while the thermal control circuit is active as indicated by the as-
sertion of PROCHOT# is the same as the maximum Icc for the processor.
11.
VTT must be provided via a separate voltage source and not be connected to VCC. This specification is measured at the land.
12.
Baseboard bandwidth is limited to 20 MHz.
13.
These parameters are based on design characterization and are not tested.
14.
This is maximum total current drawn from VTT plane by only the processor. This specification does not include the current com-
ing from RTT (through the signal line). Refer to the Voltage Regulator Down (VRD) 10.1 Design Guide For Desktop LGA775
Socket to determine the total ITT drawn by the system.
Table 2-9. VCC Static and Transient Tolerance for 775_VR_CONFIG_04A Processors
ICC (A)
Voltage Deviation from VID Setting (V)1, 2, 3
NOTES:
1.
The loadline specification includes both static and transient limits except for overshoot allowed as shown in
2.
This table is intended to aid in reading discrete points on Figure 2-2.
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) 10.1 Design Guide For Desktop LGA775 Socket for socket loadline
guidelines and VR implementation details.
