  • Transparent PXIe expansion
  • PCIe 4.0 SFF-8644 cables
  • 3U rack mountable
  • Port status LEDs
  • Copper and Fiber-optic cables
  • Microchip Gen 4.0 PFX chipset

MXP909 Product Data

The 3U MXP909 PXIe Peripheral  Module is designed to create a flexible and scalable CompactPCI Express / PXIe expansion solution. The MXP909 enables connectivity to other PXIe chassis utilizing the MXP924 PXIe switch card or to other compliant IO devices.

PCI Express Gen 4.0

The MXP909 is designed for PCIe Gen 4.0 link speeds in the backplane and via the front panel PCIe cable port. It will auto negotiate to the highest speed supported (PCIe Gen4 - Gen1) by each component connected to individual port. This allows you to mix various generation of equipment without scarifying performance between high speed components.

PCIe IO Expansion

Several PXIe systems can be interconnected to multi rack system using direct PCIe 4.0 cables. The host PXIe chassis uses one or more MXP909 cards. Each target PXIe system uses a MXP924 in the system slot. The MXP909 can also connect directly to other PCIe target devices compliant to the PCI-SIG External Cabling Specification 3.0/4.0. The MXS924 1 U Rack mount switch enables scale out to larger transparent PCIe networks. Please contact Dolphin for details.

PCIe Cable ports

The MXP909 module has a physical quad SFF-8644 PCIe cable connector to allow connectivity to external PCIe devices but only the two upper ports are available for connectivity. Both ports can be used as two independent x4 links or one x8 links. Each SFF-8644 connector has a protected 3.3V supply to support AOCs. The MXP909 is carefully designed for maximum copper cable lengths. Fiber optics extends this distance to 100 meters. More info on cable alternatives for the MXP909 switch.

Backplane support

The MXP909 follows the PXISA PXIE-1 rev 2.3 and PXISA PCIE-5 Hardware specification 1.1.
