Dual-Core Intel® Xeon® Processor 3000 Series Datasheet

Electrical Specifications

Notes:

1. Unless otherwise noted, all specifications in this table are based on estimates and simulations or empirical data. These

specifications will be updated with characterized data from silicon measurements at a later date.

2. Adherence to the voltage specifications for the processor are required to ensure reliable processor operation.

3. Each processor is programmed with a maximum valid voltage identification value (VID), which is set at manufacturing and can

not be altered. Individual maximum VID values are calibrated during manufacturing such that two processors at the same

frequency may have different settings within the VID range. Note this differs from the VID employed by the processor during a

power management event (Thermal Monitor 2, Enhanced Intel SpeedStep® Technology, or Extended HALT State).

4. These voltages are targets only. A variable voltage source should exist on systems in the event that a different voltage is required.

See Section 2.3 and Table 2-1 for more information.

5. 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 MΩ 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 oscilloscope probe.

6. Refer to Table 2-5 and Figure 2-1 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.

7. ICC_MAX specification is based on the VCC_MAX loadline. Refer to Figure 2-1 for details.

8. VTT must be provided via a separate voltage source and not be connected to VCC. This specification is measured at the land.

9. Baseboard bandwidth is limited to 20 MHz.

10.This is maximum total current drawn from VTT plane by only the processor. This specification does not include the current coming

from RTT (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 ITT drawn by the system. This parameter is based on design characterization

and is not tested.

Voltage Deviation from VID Setting (V)1, 2, 3, 4

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 2-1.

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) 11.0 Processor Power Delivery Design Guidelines For Desktop LGA775

Socket for socket loadline guidelines and VR implementation details.

4. Adherence to this loadline specification is required to ensure reliable processor operation.
