3U VPX PCI Express and Ethernet Hybrid switch

The Kontron 3U VPX PCI Express and Ethernet hybrid switch VX3905 is the ideal partner for the centralized backplane to efficiently handle a high bandwidth. It provides up to 24 Ports with 32 lane PCI Express Gen 1 / Gen 2 switching and additional 9 port gigabit Ethernet switching capabilities for the control plane. By this it offers a tenfold increase in I/O bandwidth between computing boards in High Performance Embedded Computing applications compared to VME, unleashing a new kind of applications for data processing platforms used for Radar, Sonar and general image processing.

VX3905 is available in an air-cooled version (0°C to +55°C) and in rugged conduction-cooled version (-40°C to + 85°C).
