BPG6615 PCI Express Backplane

Key Features

  • Wide Range of SBC Options
  • 1-x16 & 4-x4 PCIe I/O Cards
  • 2-64-bit/100MHz PCI-X Slots
  • 4-64-bit/66MHz PCI-X Slots

The BPG6615 PCI Express Backplane

The BPG6615 PCI Express backplane has a 14-slot form factor that enables 4U rackmount computer designs that can support a single or dual-processor PICMG 1.3 single board computer, five PCI Express and six PCI-X/PCI standard plug-in I/O cards.  Typical dual-processor SBCs used with this backplane include the BPX7059 and JXT6966 while single-processor boards include the TSB7053 and TQ9.

The x16 PCIe card slot on the BPG6615 PCI Express backplane is driven with a x16 electrical interface link direct from the SBC.  The remaining four x8 PCIe slots available on the backplane are driven with x4 links from a 24-lane PCI Express switch.  The PCIe switch also provides a x4 link that drives the dual-channel PCIe-to-PCI-X bridge which interfaces the PCI-X/PCI option card slots to the system’s single board computer.

Key features of the BPG6615 PCI Express backplane include:

  • 14-slot form factor server-class backplane ideal for 4U rackmount computer systems
  • Supports up to six PCI Express plug-in I/O cards
    • 1 – x16 PCI Express electrical / x16 mechanical connector [direct from SBC]
    • 4 – x4 PCI Express electrical /  x8 mechanical connector [driven by PCIe switch]
  • Supports up to six PCI-X/PCI plug-in I/O cards
    • 2 – 64-bit/100MHz PCI-X
    • 4 – 64-bit/66MHz PCI-X
  • Supports one PICMG 1.3 system host board and two USB 2.0 headers
  • Long-life backplane with 7+ year availability for stable system designs
The BPG6615 PCI Express backplane is designed, manufactured and supported in the USA and comes with a 5-year warranty.
