Flexible Motherboard Guidelines For The Intel Processor 9500 Series; Itanium - Intel BX80569Q9550 - Core 2 Quad 2.83 GHz Processor Datasheet

Electrical Specifications
2.6.2 Flexible Motherboard Guidelines for the Intel
Processor 9500 Series
The Flexible Motherboard (FMB) guidelines are estimates of the maximum ratings that
the processor will have over certain time periods. The ratings are only estimates as
actual specifications for future processors may differ. The processor may or may not
have specifications equal to the FMB value in the foreseeable future.

Notes:
1. The voltage specification requirements are measured across the VCCUNCORESENSE and VSSUNCORESENSE pins using an
oscilloscope set to a 100 MHz bandwidth and probes that are 1.5 pF maximum capacitance and 1 mOhms minimum impedance
at the processor socket. The maximum length of ground wire on the probe should be less than 5 mm. Ensure external noise from
the system is not coupled into the scope probe.
2. These voltages are target only. A variable voltage source should exist on systems in th e event that a different voltage is required.
See the Ararat II Voltage Regulator Module Design Guide for more information.
3. Uncore and Core voltage and Current Rating are at the Package Pad.
4. The voltage specification requirements are measured across the VCCCORESENSE and VSSCORESENSE pins using an oscilloscope
set to a 100 MHz bandwidth and probes that are 1.5 pF maximum capacitance and 1 mOhms minimum impedance at the
processor socket. The maximum length of ground wire on the probe should be less than 5 mm. Ensure external noise from the
system is not coupled into the scope probe.
5. Warm boot reset, only in downward direction.
6. Min and Max range is spec at the die for VCCIO. This range includes 35 mV p-p AC noise. It also includes any DC and AC
tolerances at package pin.
