The BPG6544 PCI Express Backplane
The BPG6544 PCI Express backplane supports a single-processor single board computer, one IOB33 PCIe link expansion module, two PCI Express, five PCI-X, two PCI and two ISA plug-in I/O cards. The unique backplane design places the PICMG 1.3 SBC slot near the center of the backplane to enable more efficient air flow within a rackmount computer chassis.
The SBC’s PCI Express links drive the PCIe card slots directly. An additional x4 PCIe link from the SBC enables a dual-channel PCIe-to-PCI-X bridge chip to interface the PCI-X slots into the system. The 32-bit/33MHz PCI slots are driven directly from the SBC’s optional edge connector D PCI interface while a PCI-to-ISA bridge is used to establish communication between the SBC and the backplane’s two ISA plug-in I/O card slots.
The eleven option card slots support standard PCIe, PCI-X, PCI and ISA plug-in I/O cards typically used in military and industrial automation systems.
Key features of the BPG6544 PCI Express backplane include:
- Supports one PICMG 1.3 combo or graphics-class single board computer
- SBC slot located near the center of the backplane improves chassis air flow
- Supports two PCI Express, five PCI-X, two PCI and two ISA cards
