Pci Express* Connectors; Ieee-1394A Connectors (Optional) - Intel BOXD945GCZL Technical Product Specification

Intel Desktop Board D945GCZ Technical Product Specification

1.7 PCI Express* Connectors

The board provides the following PCI Express connectors:
•
One PCI Express x16 connector supporting simultaneous transfer speeds up to 8 GBytes/sec
•
One PCI Express x1 connector. The x1 interface supports simultaneous transfer speeds up to
500 MBytes/sec
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

1.8 IEEE-1394a Connectors (Optional)

The optional 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. As a manufacturing option, 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.
