Intel XeonTM Processor MP
Datasheet

NOTES:
1. Unless otherwise noted, all specifications in this table apply to all processors. These specifications are based on final
characterized data.
2. A variable voltage source should exist on systems in the event that a different voltage is required. See
Section 2.5 and
3. The voltage specification requirements are measured across vias on the platform for the VCC_SENSE and VSS_SENSE pins
close to the socket with a 100 MHz bandwidth oscilloscope, 1.5 pF maximum probe capacitance, and 1 M
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 in the scope probe.
4. The processor should not be subjected to any static VCC and ICC combination wherein VCC exceeds
VCC_MID + 0.200 * (1-ICC/ICC_MAX) [V]. Moreover, VCC should never exceed VCC_MAX (VID). Failure to adhere to
this specification can shorten the processor lifetime.
5. Maximum current is defined at VCC_MID.
6. The current specified is also for AutoHALT State.
7. The instantaneous current the processor will draw while the thermal control circuit is active as indicated by the assertion
of PROCHOT#.
8. This specification applies to the PLL power pins VCCA and VCCIOPLL. See
Section 2.4.1 for details. This parameter
is based on design characterization and is not tested.
9. This specification applies to each GTLREF pin.
