BPX6620 PCI Express Backplane

Key Features

  • Wide Range of SBC Options
  • 1-x8 & 1-x4/x1 PCIe I/O Card
  • 2-64-bit/133MHz PCI-X Slots
  • 8-64-bit/100MHz PCI-X Slots

The BPX6620 PCI Express Backplane

The BPX6620 PCI Express backplane provides electrical connections for one x8 and one x4/x1 PCI Express plug-in I/O card and ten PCI-X/PCI option cards.  It supports a single or dual-processor PICMG 1.3 single board computer that drives the PCIe card slots and the PCI-X option cards via three dual-channel PCIe-to-PCI-X bridge chips.

The twelve total slots support standard PCI Express, PCI-X and universal  PCI plug-in I/O cards typically used in communication platforms.

Key features of the BPX6620 PCI Express backplane include:

  • Supports one PICMG 1.3 combo or server-class single board computer
  • Supports two PCI Express and ten PCI-X/PCI cards
    • 1 –  x8 PCI Express electrical / x16 mech. connector directly from SBC
    • 1 –  x4/x1 PCI Express electrical# / x8 mech. connector from SBC via IOB33 module Link width is SBC dependent
    • 2 – 64-bit/133MHz PCI-X
    • 8 – 64-bit/100MHz PCI-X
  • Three, dual-channel PCIe-to-PCI-X bridge chips
  • Support universal PCI plug-in I/O cards
  • Two 10/10/100/1000Base-T backplane Ethernet ports
  • Four USB 2.0 backplane I/O connections
  • ATX/EPS, terminal block and right-angle/high-current input power connector options
  • Long-life backplane with 7+ years of availability enhances system design stability
The BPX6620 PCI Express backplane is designed, manufactured and supported inthe USA, and is backed by a 5-year warranty.

Model Number


Form Factor

14-slot form factor supports a PICMG 1.3 SBC, PCIe and PCI-X option cards


Board dimensions: 12.3” x 11.9”

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.


PCI Express Slots:
One, x4 PCIe slot (x8 mechanical) from a SHB via an IOB31 module
One, x8 PCIe slot (x16 mechanical) driven directly from SHB

PCI-X/PCI Slots:
Two, PCI-X slots, 64-bit/133MHz
Eight, PIC-X/PCI slots, 64-bit/100MHz

See datasheet or mechanical layout diagram for detailed slot routing information.
