2.9 Processor DC Specifications
The following notes apply:
• The processor DC specifications in this section are defined at the processor core silicon and
not at the package pins unless noted otherwise.
• The notes associated with each parameter are part of the specification for that parameter.
• Unless otherwise noted, all specifications in the tables apply to all frequencies and cache sizes.
See Section 5 for the pin signal definitions. Most of the signals on the processor FSB are in the
AGTL+ signal group. The DC specifications for these signals are listed in Table 2-14.
Table 2-8 lists the DC specifications for the Dual-Core Intel Xeon processor 7000 series and are
valid only while meeting specifications for case temperature, clock frequency, and input voltages.
2.9.1 Flexible Motherboard (FMB) Guidelines
The FMB guidelines are estimates of the maximum values that the Dual-Core Intel Xeon processor
7000 series will reach over the product lifetime. The values are only estimates as actual
specifications for future processors may differ. The Dual-Core Intel Xeon processor 7000 series
may or may not have specifications equal to the FMB value in the foreseeable future. System
designers should meet the FMB values to ensure that their systems will be compatible with future
releases of the Dual-Core Intel Xeon processor 7000 series.
