Signal Definitions
FBD1NBICLK[C/D][P/N]0 I
These
differential pair clock signals generated from the branch one, channel C and
D of FB-DIMMs are input to the processor.
Example: FBD1NBICLKDP0 represent FB-DIMM branch 1, northbound clock input
signal of channel D and positive bit of the differential pair.
FBD0SBOCLK[A/B][P/N]0
O
These differential pair output clock signals generated from the processor are inputs
to the branch zero, channel A and B of FB-DIMMs.
Example: FBD0SBICLKAP0 represent FB-DIMM branch 0, southbound clock output
signal of channel A and positive bit of the differential pair.
FBD1SBOCLK[C/D][P/N]0
O
These differential pair output clock signals generated from the processor are inputs
to the branch one, channel C and D of FB-DIMMs.
Example: FBD1SBICLKDP0 represents FB-DIMM branch 1, southbound clock output
signal of channel D and positive bit of the differential pair.

FBD0NBI[A/B][P/N][12:0]
I
These differential pair data signals generated from the branch zero, channel A and
B of FB-DIMMs are input to the processor.
Example: FBD0NBIAP[0] represent FB-DIMM branch 0, northbound data input lane
0 signal of channel A and positive bit of the differential pair.
FBD0NBI[A/B][P/N][13]
I
These signals are spare lanes, and are intended for Reliability, Availability, and
Serviceability (RAS) coverage on the Intel

Itanium
®
9500 Processor Series. These
signals are not used by Intel
