SMI Specifications for 4.8 GT/s
The applicability of this section applies to Intel
®
QPI for the Intel
®
Itanium
®
Processor
9300 Series. This section contains information for Intel
®
QPI slow boot up speed
(1/4 frequency of the reference clock) and processor’s normal operating frequency, 4.8
GT/s, for Intel
®
QPI and Intel
®
SMI.
For Intel
®
QPI slow boot up speed, the signaling rate is defined as 1/4 the rate of the
system reference clock. For example, a 133 MHz system reference clock would have a
forwarded clock frequency of 33.33 MHz and the signaling rate would be 66.67 MT/s.
The transfer rates available for the processor are shown in
. Transmitter and
receiver parameters for Intel
®
QPI slow mode, Intel
®
QPI and Intel
®
SMI are shown in
and
respectively.
