PEX431 Multi-fabric Switch

Multi-fabric switch and XMC carrier card for VPX systems

PEX431 Multi-fabric Switch

Overview


Designed to enable the development of complex, scalable, high performance 3U VPX systems in today’s increasingly-connected military/aerospace world, the PEX431 is characterized by significant flexibility. The PEX431 Multi-Fabric Switch and XMC Carrier Card allow designers to build complex VPX systems with multiple single board computers and multiple I/O modules. PEX431 supports PCIe switching, GigE switching and the ability to host a XMC mezzanine.

The PCI Express switch of the PEX431 allows up to six ports of 4-lane PCI Express to be connected to a non-blocking line-speed switch, such that a scalable, complex system architecture can be created. In order to support systems requiring interconnection of more than six hosts, multiple PEX431 boards may be daisy-chained together.

The PEX431 has an unmanaged Layer 2 Gigabit Ethernet Switch that offers up to nine ports, of which up to eight can be in 1000BASE-BX and up to two can be in 1000BASE-T.

The PEX431 is capable of carrying XMC modules and can be configured for 8-lane PCI Epress at the VPX backplane connector. The XMC option is not available with the Ethernet Switching option.

From a software perspective, each PCI Express port is a virtual PCI-to-PCI bridge device, with its own set of PCI Express configuration registers.
