Electrical Specifications

Intel® Xeon® Processor 7500 Datasheet, Volume 1
Notes:
1.
The Vcc
_MIN
and Vcc
_MAX
loadlines represent static and transient limits. Please see
for Vcc overshoot specifications.
2.
The loadlines specify voltage limits at the die. Die Vcc voltage is available at the Vcoresense and
Vsscoresense lands and should be measured there. Voltage regulation feedback for voltage regulator
circuits must be taken from the processor Vcoresense and Vsscoresense lands. Voltage regulation feedback
for voltage regulator circuits must also be taken from processor VCCCORESENSE and VSSCORESENSE
lands. Refer to the Voltage Regulator Module (VRM) and Enterprise Voltage Regulator Down (EVRD) 11.1
Design Guidelines for socket load line guidelines and VR implementation. Please refer to the appropriate
platform design guide for details on VR implementation
