Electrical Specifications
6.10.1.2 DMI2/PCI Express AC Specifications
Intel® Xeon® E7 v2 processor AC specifications for the PCI Express* are available in
the PCI Express® Base Specification 2.0 and 1.0. This document will provide only the
processor exceptions to the PCI Express® Base Specification 2.0 and 1.0.
6.10.1.3 Intel® QuickPath Interconnect AC Specifications
Intel® QuickPath Interconnect specifications are defined at the processor lands.
Intel® Xeon® E7 v2 processor AC specifications for the Intel® QPI interface are
available in the Intel® QuickPath Interconnect V1.1 Base Electrical Specification and
Validation Methodologies. This document will provide only the processor exceptions to
the Intel® QuickPath Interconnect V1.1 Base Electrical Specification and Validation
Methodologies.
6.10.1.4 SMBus Signal AC Specifications
Intel® Xeon® E7 v2 processor AC specifications for the SMBus are available in the
System Management Bus (SMBus) Specification, Revision 2.0. This document will
provide only the processor exceptions to the System Management Bus (SMBus)
Specification, Revision 2.0.
6.10.1.5 Reset and Miscellaneous Signal AC Specifications
For a power-on Reset, RESET_N must stay active for at least 3.5 millisecond after V
CC
and BCLK{0/1} have reached their proper specifications. RESET_N must not be kept
asserted for more than 100 ms while PWRGOOD is asserted. RESET_N must be held
asserted for at least 3.5 millisecond before it is deasserted again. RESET_N must be
held asserted before PWRGOOD is asserted. This signal does not have on-die
termination and must be terminated on the system board.
6.11 AC Timing Waveforms
