Electrical Specifications
2.13 Processor DC Specifications
The processor DC specifications in this section are defined at the processor die
(pads) unless noted otherwise. See Table 4-1 for the Quad-Core Intel® Xeon®
Processor 5300 Series land listings and Table 5-1 for signal definitions. Voltage and
current specifications are detailed in Table 2-12. For platform planning refer to
Table 2-13, which provides V
CC
Static and Transient Tolerances. This same information
is presented graphically in Figure 2-7, Figure 2-8 and Figure 2-9.
The FSB clock signal group is detailed in Table 2-21. The DC specifications for the
AGTL+ signals are listed in Table 2-16. Legacy signals and Test Access Port (TAP)
signals follow DC specifications similar to GTL+. The DC specifications for the
PWRGOOD input and TAP signal group are listed in Table 2-17.
Table 2-12 through Table 2-18 list the DC specifications for the processor and are valid
only while meeting specifications for case temperature (T
CASE
as specified in Section 6),
clock frequency, and input voltages. Care should be taken to read all notes associated
with each parameter.
2.13.1 Flexible Motherboard Guidelines (FMB)
The Flexible Motherboard (FMB) guidelines are estimates of the maximum values the
Quad-Core Intel® Xeon® Processor 5300 Series will have over certain time periods.
The values are only estimates and actual specifications for future processors may differ.
Processors may or may not have specifications equal to the FMB value in the
foreseeable future. System designers should meet the FMB values to ensure their
systems will be compatible with future processors.
