The BPG8155 PCI Express backplane, when paired with a PCIe 3.0 capable single board computer like the BXT7059, delivers PCIe Gen3 link speeds and expanded I/O card bandwidth to military computing, industrial automation, medical, telecommunications and GPU computing applications. This backplane supports one PICMG® 1.3 single board computer and up to twelve PCI Express I/O cards. Eleven of these option card slots are PCIe 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.

The PCIe 3.0 link design of the BPG8155 PCI Express backplane supports a x16 PCIe Gen3 link from Trenton’s BXT7059 system host board as well as future PCIe Gen3 SHBs. The backplane’s two, 16-port/64-Lane Gen3 switches deliver PCIe 3.0 links to option card slots PCIe2 through PCIe12 while PCIe1 is driven with a PCIe 2.0 link from the SHB. The switches and the BXT7059 automatically establish communications with either PCI Express 3.0, 2.0 or 1.1 option cards. All option card slots utilize x16 mechanical connectors. Card slots PCIe5 and PCIe9 are driven with x16 electrical links while card slots PCIe2, 6 and PCIe12 are driven with x8 electrical links. Card slots PCIe3, 4, 7, 8, 10 and 11 are driven with x4 PCIe 3.0 links. PCIe1 is a slot driven with a x4 interface from the SHB’s B0 link. The BPG8155 backplane has a right angle ATX/EPS and two 12V AUX power connectors plus a terminal block to meet expanded system power demands.

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.

The BPG8155 PCI Express backplane is designed and manufactured in Trenton’s ISO 9001:2008 registered facilities and supported from within the USA. This 14-slot, PCIe Gen3 backplane is supported by Trenton’s 5-year factory warranty.
