Quad-Core Intel® Xeon® Processor 5400 Series Electrical Specifications . Figure 2-2. 3. The voltage specification requirements are measured across the VCC_DIE_SENSE and VSS_DIE_SENSE lands and across the VCC_DIE_SENSE2 and VSS_DIE_SENSE2 lands with an oscilloscope set to 100 MHz bandwidth, 1.5 pF maximum probe capacitance, and 1 MΩ 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 must not be subjected to any static VCC level that exceeds the VCC_MAX associated with any particular current. Failure to adhere to this specification can shorten processor lifetime. 5. ICC_MAX specification is based on maximum VCC loadline. Refer to Figure 2-7, Figure 2-8, Figure 2-9 and Figure 2-10 for details. The processor is capable of drawing ICC_MAX for up to 10 ms. Refer to Figure 2-1 for further details on the average processor current draw over various time durations. 6. FMB is the flexible motherboard guideline. These guidelines are for estimation purposes only. See Section 2.13.1 for further details on FMB guidelines. 7. This specification represents the total current for GTLREF_DATA_MID, GTLREF_DATA_END, GTLREF_ADD_MID, and GTLREF_ADD_END. 8. VTT must be provided via a separate voltage source and must not be connected to VCC. This specification is measured at the land. 9. Minimum VCC and maximum ICC are specified at the maximum processor case temperature (TCASE) shown in Figure 6-2 and Figure 6-3. 10. This specification refers to the total reduction of the load line due to VID transitions below the specified VID. 11. Individual processor VID values may be calibrated during manufacturing such that two devices at the same frequency may have different VID settings. 12. This specification applies to the VCCPLL land. 13. Baseboard bandwidth is limited to 20 MHz. 14. ICC_TDC is the sustained (DC equivalent) current that the processor is capable of drawing indefinitely and should be used for the voltage regulator temperature assessment. The voltage regulator is responsible for monitoring its temperature and asserting the necessary signal to inform the processor of a thermal excursion. Please see the applicable design guidelines for further details. The processor is capable of drawing ICC_TDC indefinitely. Refer to Figure 2-1 for further details on the average processor current draw over various time durations. This parameter is based on design characterization and is not tested. 15. This is the maximum total current drawn from the VTT plane by only one processor with RTT enabled. This specification does not include the current coming from on-board termination (RTT), through the signal line. Refer to the appropriate platform design guide and the Voltage Regulator Design Guidelines to determine the total ITT drawn by the system. This parameter is based on design characterization and is not tested. 16. ICC_VTT_OUT is specified at 1.1 V. 17. ICC_RESET is specified while PWRGOOD and RESET# are asserted. 18. The Quad-Core Intel® Xeon® Processor X5482 is intended for dual processor workstations only.
