VPX3-663 SOSA-Aligned PCIe Gen 3 & 10G Ethernet Switch

PCIe Gen 3 and 10G Ethernet Hybrid Switch

For SWaP-Constrained C5ISR applications

The VPX3-663 hybrid switch combines PCI Express 3.1 and 10 Gigabit Ethernet switching in a single 3U VPX module. Ideal for size, weight, and power (SWaP)-constrained platforms, the VPX3-663 provides single-slot connectivity for high-performance processing systems that combine SBC, DSP, GPU, FPGA, I/O, or storage modules.

  • Open Standards Architectures
  • High-Performance 3U VPX Connectivity
  • Flexible PCIe Connectivity
  • Feature-Rich Ethernet

Open Standards Architectures

Designed to eliminate interoperability challenges between COTS modules, the VPX3-663 complies to OpenVPX 6F6U and 6F8U switch module profiles and is developed in alignment with The Open Group Sensor Open Systems Architecture™ (SOSA) Technical Standard.

High-Performance 3U VPX Connectivity

The VPX3-663 combines a PCIe Gen 3.1 switch and 10G backplane Ethernet switch in a single 3U module, enabling you to connect between a wide range of module types – including those with earlier Gen 1 or Gen 2 PCIe interfaces. With the VPX3-663, designers can create switched networks that allow any module in the system to connect to any other at full rate, eliminating the bottlenecks that result from daisy-chaining.

Flexible PCIe Connectivity

Featuring a powerful non-transparent bridging capability, the VPX3-663 PCIe switch enables systems with multiple processor modules to share a resource or communicate directly from host to host, using the VPX3-663 as a PCIe data plane fabric. When configured for fan-out topologies, the VPX3-663 can act as an expansion plane switch, allowing a single host processor to communicate at full rate with multiple downstream cards, or share access between multiple hosts.

Feature-Rich Ethernet

The VPX3-663 features a fully managed Ethernet switch with a range of networking features to enable traffic management and enforce security policies. Its 10Gbps backplane Ethernet interfaces provide a high-performance control plane for the latest processing modules.

What is the SOSA Technical Standard?

The SOSA Technical Standard defines a common framework for transitioning sensor systems to an open systems architecture. The SOSA standard leverages OpenVPX to define card profiles with specifications for features such as pinouts, Ethernet capabilities, and serial ports.
