Processor DC Specifications
The processor DC specifications in this section are defined at the processor core (pads) unless
noted otherwise. See for the Intel Xeon processor MP on the 0.13 micron process processor pin
listings and
Section 9.2 for the signal definitions. The voltage and current specifications for all
versions of the processor are detailed in
Table 6. For platform planning refer to
Figure 3. Notice
that the graphs include Thermal Design Power (TDP) associated with the maximum current levels.
The DC specifications for the AGTL+ signals are listed in
Table 9.The system bus clock signal group and the SMBus interface signal group are detailed in
Table 8and
Table 12, respectively. The DC specifications for these signal groups are listed in
Table 12.Table 7 through
Table 11 list the DC specifications for the Intel Xeon processor MP on the
0.13 micron process processor and are valid only while meeting specifications for case temperature
(TCASE as specified inSection 5), clock frequency, and input voltages. Care should be taken to read all notes associated with each parameter. )
NOTES:
1. Unless otherwise noted, all specifications in this table are based on the latest silicon measurements available
at the time of publication.
2. These voltages are targets only. A variable voltage source should exist on systems in the event that a
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 mohm 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.
