VPX Chassis — Backplane
Backplane
VPX Backplane is an 8-slot modular infrastructure board, developed for electronic warfare, radar, and mission computer systems, based on VITA/OpenVPX/SOSA principles. It provides high-speed data, control, management, clock, and power distribution among all modules in the chassis over a single printed circuit board.
- Slot:8-Slot
- Standard:OpenVPX
- Compliance:SOSA Compliant
- Fabric:PCIe Gen3
- VITA:VITA 62
