The BPG8150 PCI Express Small Form Factor Backplane
The BPG8150 PCI Express small form factor backplane utilizes a robust PCIe 3.0 link design to support two x16 PCIe Gen3 links from Trenton’s current dual-processor, BXT7059 system host board with the PEX10 PCIe link expansion option card installed. The backplane’s two, PCIe Gen3 switches deliver PCIe 3.0 links to six option card slots. A seventh card slot is driven with PCIe 2.0 B0 link from the BXT7059 SHB.
The BPG8150 PCIe small form factor backplane is also designed for future dual-processor PCIe Gen3 SHBs that will enable all seven slots to be driven by PCI Express Gen3 links. Both the PCI Express Gen3 switches and the BXT7059 automatically establish communications with either PCI Express 3.0, 2.0 or 1.1 option cards. This I/O card flexibility inherent in the BPG8150 PCIe small form factor backplane makes this product an ideal building block in military computing, industrial automation, medical diagnostics, telecommunications & GPU computing applications.
The backplane’s 16-port/64-lane and 5-port/48-lane PCIe Gen3 switches deliver PCIe 3.0 links to all option card slots except slot PCIe3, card slot PCIe3 is currently driven with a PCIe 2.0 link directly from the BXT7059 SHB. Both the switches and the BXT7059 automatically establish communications with either PCI Express 3.0, 2.0 or 1.1 option cards, and all option card slots utilize x16 mechanical connectors. Card slots PCIe1, PCIe2, PCIe6, and PCIe7 are driven with x16 electrical links making these four slots ideal for high-end video, graphics and GPU cards. Card slots PCIe4 and PCIe5 are driven with x8 electrical links, while the PCIe3 slot is driven with a x4 PCI Express interface connection from the SHB’s B0 link. The BPG8150 backplane has a right angle ATX/EPS and a 12V AUX power connector plus an optional terminal block is available to meet expanded system power demands.
PCIe links integrated into the current BXT7059 SBC; as well as future Trenton dual-processor SBC’s, 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.

Small form factor [7.9″/200mm (W) x 12.9″/327mm (D)] supports one, dual-processor PICMG 1.3 single board computer equipped with a PEX10 option card and up to seven PCI Express option cards. All card slots use x16 PCIe mechanical connectors. The backplane’s two PCIe Gen3 switches deliver PCI Express 3.0 electrical interfaces to six of the backplane’s seven slots.
Board dimensions: 7.9” x 12.9” (200.6mm x 327.6mm) small form factor backplane
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.
The seven available PCI Express option card slots on the BPG8150 backplane are configured as follows:
4 – x16 PCI Express 3.0/2.0/1.1 electrical / x16 mechanical connectors
2 – x8 PCI Express 3.0/2.0/1.1 electrical / x16 mechanical connectors
1 – x4 PCI Express 2.0/1.1 electrical / x16 mechanical connector (Note: This slot is driven by SBC link B0)
