BPX6571 PCI Express Backplane

Key Features

  • Ideal For Telecommunications
  • Wide Range of SBC Options
  • 1-x8 & 1-x4 PCI Express Slots
  • 16-64-bit/66MHz PCI-X Slots

The BPX6571 PCI Express Backplane

The BPX6571 PCI Express backplane provides electrical connections for one x8, one x4 PCI Express plug-in I/O card and sixteen 64-bit/66MHz PCI-X/PCI option cards.  The backplane supports a single or dual-processor PICMG 1.3 single board computer that drives all PCIe card slots directly and the PCI-X and PCI option cards via two PCIe-to-PCI-X bridge chips.  The eighteen total slots support standard PCIe, PCI-X and PCI plug-in I/O cards typically used in communication platforms.

Key features of the BPX6571 PCI Express backplane include:

  • Supports one PICMG 1.3 combo or server-class single board computer
  • Supports two PCI Express and sixteen PCI-X/PCI cards
    • 1 –  x8 PCI Express electrical / x16 mech. connector
    • 1 –  x4 PCI Express electrical /  x8 mech. connector
    • 16 – 64-bit/66MHz PCI-X
  • Two, dual-channel PCIe-to-PCI-X bridge chips
  • Long-life backplane with 7+ years of availability enhances system design stability
The BPX6571 PCI Express backplane is designed, manufactured and supported inthe USA, and backed by a 5-year warranty.
