The BPG8194 PCI Express Backplane

The BPG8194 PCI Express backplane features eight Gen3 PCI Express® x16 electrical interfaces. The BPG8194 PCI Express backplane design is an ideal system technology choice in military command and control centers, industrial automation computers, video display wall controllers and GPU rackmount computer systems. This large format or 20-slot form factor backplane supports one PICMG 1.3 SBC and thirteen x16 PCI Express I/O option card slots. Each option card slot uses a PCIe x16 mechanical connector to maximize system design flexibility.

Trenton’s BPG8194 PCI Express backplane features eight (8) x16 PCI Express electrical interface links that enable system designers to support multiple high-end video/graphics or GPU cards in a single rackmount computer system. There are thirteen (13) total slots to support standard PCI Express plug-in I/O cards. A single-processor Trenton THD8141 SBC or a dual-processor BXT7059 SBC has the PCIe links to drive the backplane integrated into the CPUs.

Trenton SBCs also support the PCI Express auto-training function to ensure SBC-to-option card communications regardless of PCIe interface type or link width. This SBC and backplane design feature maximizes system flexibility by enabling system support for standard PCIe 3.0, 2.0 or 1.1 option cards having various PCIe electrical interface link widths such as x16, x8, x4 and x1.

Key features of the BPG8194 PCI Express backplane include:

  • A building block for scalable military and industrial computers, video wall controllers and GPU computing solutions
  • Thirteen Eighteen total PCIe 3.0 option card slots available in PCI Express backplane application
    • 8 – x16 PCI Express 3.0 electrical / x16 mech. connectors
    • 5 – x4 PCI Express 3.0/ electrical / x16 mech. connectors*
  • Optimized PCI Express 3.0 link design maximizes data throughput while minimizing data latency
  • Long life cycle with 7+ year backplane availability
*The PCIe1 card slot may operate as a x4 PCIe 2.0/1.1 link interface depending on SBC

The BPG8194 PCI Express backplane is designed and manufactured in the USA, and backed by our 5-year factory warranty.


Tech Specs

Model Number


Form Factor

Large format, i.e. 20-slot, form factor backplane supports one combo or graphics-class, PICMG 1.3 SHB and up thirteen PCI Express option cards. All card slots are designed for the Gen3 PCIe electrical interface and are equipped with x16 PCIe mechanical connectors. Eight of the card slots are driven with Gen3 PCI Express x16 electrical interfaces and the remaining five slots support a x4 PCIe electrical interface.


Board dimensions: 16.4” 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.


Graphics: Eight PCIe x16 and five PCIe x4 (all x16 mechanical) slots, all card slots are PCIe Gen3 capable

Note 1:
Backplane slot PCIe1 supports a PCIe x4 electrical link direct from the SBC. This link may may operate as a Gen2 PCIe link interface depending on the system host board’s B0 link.
Note 2:
Backplane slots PCIe2 through PCIe13 are downstream of the PCIe Gen3 switches and will operate as Gen3 interfaces for PCIe Gen3 capable option cards regardless of the SHB interface type.
Note 3:
Card slots PCIe2, 3, 4, 5, 7, 9, 11 and PCIe13 use PCIe x16 electrical interfaces. Video, graphics or GPU cards with a x16 PCI Express electrical interface should be connected into these backplane slots in order to take full advantage of the x16 link speed.
