BPX6610 PCI Express Backplane

Key Features

  • Wide Range of SBC Options
  • 2 – x8 & 4 – x4 PCIe I/O Cards
  • 2 – 64-bit/100MHz PCI-X Slots
  • 4 – 64-bit/66MHz PCI-X Slots

The BPX6610 PCI Express Backplane

The BPX6610 PCI Express backplane has a 14-slot form factor that enables 4U rackmount computer designs that can support a single or dual-processor PICMG 1.3 single board computer, six PCIe and six PCI-X/PCI standard plug-in I/O cards.  Some typical dual-processor single board computers used with the BPX6610 backplane include the BPX7059 and JXT6966 while the single-processor boards include the TSB7053 and BXTS7059.

Two of the PCIe card slots on the PCI Express backplane are driven with interface links direct from the SBC.  The remaining four x8 PCIe slots available on the backplane are driven with x4 links from a 24-lane PCI Express switch.  The PCIe switch also provides a x4 link that drives the dual-channel PCIe-to-PCI-X bridge which interfaces the PCI-X/PCI option card slots to the SBC.

Key features of the BPX6610 PCI Express backplane include:

  • 14-slot form factor server-class backplane ideal for 4U rackmount computer systems
  • Supports up to six PCI Express plug-in I/O cards
    • 1 – x8 PCI Express electrical / x16 mechanical connector [direct from SBC]
    • 1 – x8 PCI Express electrical /  x8 mechanical connector [direct from SBC]
    • 4 – x4 PCI Express electrical /  x8 mechanical connector [driven by PCIe switch]
  • Supports up to six PCI-X/PCI plug-in I/O cards
    • 2 – 64-bit/100MHz PCI-X
    • 4 – 64-bit/66MHz PCI-X
  • Supports one PICMG 1.3 system host board and two USB 2.0 headers
  • Long-life backplane with 7+ year availability for stable system designs
The BPX6610 PCI Express backplane is designed, manufactured and supported in the USA and backed by a 5-year warranty
