Key Features

Key features of the BPX8087 PCI-X/PCI Express backplane include:

  • 2U butterfly form factor backplane supports a wide variety of 2U chassis designs
  • Side A of this server-class backplane supports one PICMG 1.3 SBC
  • Side A supports two 64-bit/66MHz PCI-X slots
  • Side B includes two 64-bit/66MHz PCI-X slots and one x8 PCI Express slot driven with a x4 link from an SBC like a TSB7053
  • Side B includes four general purpose USB I/O interfaces
  • PICMG 1.3 backplane with vertical ATX/EPS and +12 AUX power connectors

The BPX8087 PCI Express backplane is designed and manufactured in Trenton Systems’ ISO 9001:2008 registered facilities and supported from within the USA.  This butterfly form factor PCIe backplane is supported by a 5-year factory warranty.

Tech Specs

Model Number


Form Factor

2U Butterfly, one segment


Board dimensions: 12.9″ x 3.31″

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-X Slots – Side A
Two, 64-bit/66MHz PCI-X slots driven from a dual-channel PCIe-to-PCI-X bridge with the bridge driven by a direct x16 PCIe link from the SBC

PCI-X and PCI Express Slots – Side B
Two, 64-bit/66MHz PCI-X slots driven from the bridge and one, x4 PCIe slot (x8 mechanical) driven directly from the SBC

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

Suggested SHB/SBCs

Single-processor SBCs: TSB7053 and TQ9

Note: Dual-processor single board computers such as the BXT7059 and JXT6966, and their single processor BXTS7059 and JXTS6966 variations may be used with the BPX8087 backplane.  However, backplane slot SLTA2 (64-bit/66MHz PCI-X) on side A will be obstructed when using these SBCs and the other PCI-X slot on side A may not be usable with certain I/O option cards.
