The BPX8093 PCI Express Backplane

The BPX8093 PCI Express backplane, when paired with a PCIe 3.0 capable single board computer like the BXT7059, delivers PCI Express Gen3 link speeds and expanded I/O card bandwidth to military computing, industrial automation, medical diagnostics, communications or GPU computing applications.  This backplane supports one PICMG® 1.3 single board computer and up to ten PCI Express I/O cards and nine of these option card slots are PCI Express 3.0 capable.  Each option card slot uses a x16 PCIe mechanical connector to maximize system design flexibility by supporting a wide range of standard PCI Express I/O cards.

This PCI Express backplane features six x8 PCI Express 3.0 electrical interface links if paired with a dual-processor BXT7059 single board computer and outfitted with an optional PEX10 & IOB33 PCIe link expansion option cards.  This backplane and SBC combination enables system designers to support multiple high-end video or GPU cards within a single rackmount computer. This white paper on Optimizing PCIe3 Backplane Design for Performance and Reliability provides valuable information on the design challenges that must be met for high-performance computing platforms which incorporate PCIe Gen3 backplanes.

Three additional x4 PCIe Gen3 I/O card slots are available on this BPG8093 PCIe backplane.  One x4 PCIe 2.0 slot is also available resulting in a total of 10 PCI Express I/O card slots on the backplane.  Additional PCI Express link expansion slots are included to support the PEX10 and IOB33 option cards installed on the single board computer.

PCIe links integrated into the CPUs on the BXT7059 SBC automatically match an option card’s PCI Express link type and speed via the interface’s built-in auto-training capability.  This SBC and backplane design feature maximizes system flexibility by enabling system support for standard PCI Express 3.0, 2.0 or 1.1 option cards having various PCIe electrical interfaces such as x16, x8, x4 and x1 PCIe links.

Key features of the BPX8093 PCI Express backplane include:

  • Ideal PCI Express backplane for PCIe Gen3 video processing and GPU computing
  • Features multiple x8 and x4 PCI Express 3.0 option card slots
  • Ten total PCIe option card slots available in PCI Express backplane applications
    • 6 – x8 PCI Express 3.0/2.0/1.1 electrical / x16 mech. connectors (Note: DP SBC with PEX10 needed for two of these slots)
    • 2 – x4 PCI Express 3.0/2.0/1.1 electrical / x16 mech. connectors
    • 1 – x4 PCI Express 2.0/1.1 electrical / x16 mech. connector (Note: This slot is driven by SBC link B0)
    • 1 – x4/x1 PCI Express 3.0/2.0/1.1 electrical / x16 mech. connector (Note: An IOB33 on the SBC is required for this slot)
  • Innovative 5-port/48-lane PCIe Gen3 switch
  • IOB33 and PEX10 PCIe link expansion slots
  • PCI Express 3.0 retimers ensure link communication reliability
  • Long life cycle with 7+ year backplane availability
The BPX8093 PCI Express backplane is designed and manufactured in the USA, and backed by our 5-year factory warranty.

Model Number


Form Factor

14-slot form factor supports one combo or server-class, PICMG 1.3 SBC and up to ten PCI Express option cards.  All card slots use x16 PCIe mechanical connectors and six of these slots are driven with PCI Express 3.0 electrical interfaces from a Trenton BXT7059 single board computer.


Board dimensions: 12.3” x 12.9” with a minimum drive tower cut-out of 14.53 square inchesThe 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.


Server:  Six x8 and three x4 PCIe 3.0 electrical interfaces plus one x4 PCIe 2.0 interface, with all card slots featuring x16 mechanical connectors

Note 1:
Optional IOB33 module required to provide a x4 PCIe 3.0 electrical link to backplane slot PCIe4 from a BXT7059 SBC.  The PCIe link width and interface type is determined by the specific single board computer used with the backplane.
Note 2:
Optional PEX10 module required to provide two x8 PCIe 3.0 electrical links to backplane slots PCIe1 and PCIe3 from a BXT7059 dual-processor SBC.
Note 3:
Backplane slot PCIe2 operates as PCIe 2.0/1.1 slot.
Note 4:
PCI Express link training is fully supported on the BPX8093 backplane.  This allows any PCIe to function in any backplane slot.  PCI Express 3.0 link speeds are possible in all backplane slots except PCIe2.

SHB Configuration

A dual-processor, server-class PICMG 1.3 single board computer such as the BXT7059 with optional PEX10 and IOB33 plug-in PCIe link expansion modules ensures that all card slots are active and being driven with the maximum number of PCI Express 3.0 electrical interfaces possible.

Power Connectors

ATX/EPS power source – one right-angle 24-position ATX/EPS connector
+12V AUX power source – two right-angle 8-position connectors
Extended power source – one 10-position terminal block to supply additional power if needed

Power Indicators

+5V, +5V AUX, +3.3V, +1.6V, +12V, +1V, and +0.9V power connection and status


PCIe 3.0 link status LEDs 10, 11, 12, 13, and 14 provide a visual check on the operational speed of the backplane’s critical PCIe links.

LED10 – PCIe link speed from SBC to PCIe 3.0 switch LED11 – PCIe link speed to card slot PCIe7 LED12 – PCIe link speed to card slot PCIe8 LED13 – PCIe link speed to card slot PCIe9 LED14 – PCIe link speed to card slot PCIe10

If these LEDs are on solid then the link is operating at the PCIe 3.0 interface speed.  See page 2 of the BPX8093 product data sheet located under the DOWNLOADS tab for more information.
