Pci Express* Connectors; Ieee-1394A Connectors - Intel D945PWM Technical Product Specification

1.6 PCI Express* Connectors

The board provides the following PCI Express connectors:
•
One PCI Express x16 connector supporting simultaneous transfer speeds up to 4 GBytes/sec of
peak bandwidth per direction and up to 8 GBytes/sec concurrent bandwidth
•
Two PCI Express x1 connectors. The x1 interfaces support simultaneous transfer speeds up to
250 Mbytes/sec of peak bandwidth per direction and up to 500 MBytes/sec concurrent
bandwidth
The PCI Express interface supports the PCI Conventional bus configuration mechanism so that the
underlying PCI Express architecture is compatible with PCI Conventional compliant operating
systems. Additional features of the PCI Express interface include the following:
•
Support for the PCI Express enhanced configuration mechanism
•
Automatic discovery, link training, and initialization
•
Support for Active State Power Management (ASPM)
•
SMBus 2.0 support
•
Wake# signal supporting wake events from ACPI S1, S3, S4, or S5
•
Software compatible with the PCI Power Management Event (PME) mechanism defined in the
PCI Power Management Specification Rev. 1.1

1.7 IEEE-1394a Connectors

The IEEE-1394a interface addresses interconnection of both computer peripherals and consumer
electronics. The IEEE-1394a interface provides a throughput ranging from 100 Mbits/sec to
400 Mbits/sec. The board includes three IEEE-1394a connectors as follows:
•
One IEEE-1394a connector located on the back panel.
•
Two IEEE-1394a front-panel connectors located on the component side.
