Intel Xeon Processor MP with up to 2MB L3 Cache
2-11
Electrical Specifications
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
(T
CASE 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 V
CC_SENSE and
V
SS_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.
4. Refer to
Figure 3 as appropriate for the particular Intel Xeon processor MP on the 0.13 micron process
processor of interest. The processor should not be subjected to any static VCC level that exceeds the
VCC_MAX associated with any particular current. Moreover, Vcc should never exceed VCC_VID. Failure to
adhere to this specification can shorten the processor lifetime.
5. Maximum current is defined at V
CC_max.
6. The current specified is also for AutoHALT State.
7. The maximum instantaneous current the processor will draw while the thermal control circuit is active as
indicated by the assertion of PROCHOT#.
