Technical Product Specification

Intel® Server System SC5650HCBRP TPS Functional Architecture
Revision 1.2
Intel order number E81443-002
45
3.5 PCI Subsystem
The primary I/O buses for the server board of Intel
®
Server System SC5650HCBRP are PCI,
PCI Express* Gen1, and PCI Express* Gen2 with six independent PCI bus segments.
PCI Express* Gen1 and Gen2 are dual-simplex point-to-point serial differential low-voltage
interconnects. A PCI Express* topology can contain a Host Bridge and several endpoints (I/O
devices). The signaling bit rate is 2.5 Gb/s one direction per lane for Gen1 and 5.0 Gb/s one
direction per lane for Gen2. Each port consists of a transmitter and receiver pair. A link between
the ports of two devices is a collection of lanes (x1, x2, x4, x8, x16, and so forth). All lanes
within a port must transmit data using the same frequency. The PCI buses comply with the PCI
Local Bus Specification, Revision 2.3.
The following tables list the characteristics of the PCI bus segments. Details about each bus
segment follow the tables.
