NOTES:

1. These voltages are targets only. A variable voltage source should exist on systems in the event that a different

voltage is required. See Section 2.6 and Table 4 for more information.

2. The voltage specification requirements are measured across vias on the platform for the V

CC_SENSE

and

SS_SENSE

pins close to the socket with a 100 MHz bandwidth oscilloscope, 1.5 pF maximum probe

capacitance, and 1 milliohm 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.

3. The processor should not be subjected to any static V

level that exceeds the V

CC_MAX

associated with any

particular current. Moreover, Vcc should never exceed V

CC_VID

. Failure to adhere to this specification may

shorten the processor lifetime.

4. Maximum current is defined at V

CC_MAX

5. The current specified is also for AutoHALT State.

6. The maximum instantaneous current the processor may draw while the thermal control circuit is active as

indicated by the assertion of PROCHOT#.

7. This specification applies to the PLL power pins VCCA and VCCIOPLL. See Section 2.5 for details. This

parameter is based on design characterization and is not tested

8. This specification applies to each GTLREF pin.

9. The loadlines specify voltage limits at the die measured at V

CC_SENSE

and V

SS_SENSE

pins. Voltage regulation

feedback for voltage regulator circuits must be taken from processor V

and V

pins.

10.Adherence to this loadline specification is required to ensure reliable processor operation.

11.VID_V

is required for correct operation of the Low Voltage Intel

Xeon™ Processor VID and BSEL logic. Refer

to Figure 16 for details.
