BPG6600 PCI Express Backplane

Key Features

  • Wide Range of SBC Options
  • 1-x16 & 1-x4/x1 PCIe I/O Card
  • 6-64-bit PCI-X I/O Cards
  • 4-32-bit/33MHz PCI Slots

The BPG6600 PCI Express Backplane

The BPG6600 PCI Express backplane supports a single-processor single board computer, one IOB33 PCIe link expansion module, two PCI Express and ten PCI-X/PCI plug-in I/O cards.  The unique backplane design places the PICMG® 1.3 single board computer 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.  Twelve option card slots on this PCI Express backplane support PCIe, PCI-X and PCI plug-in I/O cards typically used in military and industrial automation platforms.

Key features of the BPG6600 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 and fourteen PCI-X/PCI cards
    • 1 –  x16PCI Express electrical / x16 mech. connector
    • 1 –  x1/x4 PCI Express electrical# /  x8 mech. connector From IOB33 module on the SBC — link width is SBC dependent
    • 2 – 64-bit/100MHz PCI-X
    • 4 – 64-bit/66MHz PCI-X
    • 4 – 32-bit/33MHz PCI
  • One dual-channel PCIe-to-PCI-X bridge chip
  • Long-life backplane with 7+ years of availability enhances system design stability
The BPG6600 PCI Express backplane is designed, manufactured and supported in the USA, and backed by a 5-year warranty.

Form Factor

14-slot factor, one segment


Board dimensions: 12.3” x 12.9”

The nominal backplane thickness is 0.080”; however, the backplane mounting holes are recessed 0.018” on the bottom to provide an effective PCB thickness of 0.062” for use in the chassis design process.


PCI Express Slots
One, x4/x1 PCIe slot (x8 mechanical) from SBC via an IOB33 module
One, x16 PCIe slot (x16 mechanical) driven directly from SBC

Note:  A TSB7053 SBC provides a x4 PCIe link to slot PCIe1 and a TQ9 or TML provides a x1 link

Four, PCI-X/PCI slots, 64-bit/66MHz
Two, PCI-X/PCI slots, 64-bit/100MHz
Four, PCI slots, 32-bit/33MHz

See datasheet or mechanical layout diagram for detailed slot routing information.
