Elma Bustronic Corp. in Fremont, Calif., has developed a 5-slot VPX backplane with a mesh topology with a theoretical slot-to-slot bandwidth of over 5,000 megabytes per second. The backplane was designed with a 20-layer controlled-impedance stripline design. Elma Bustronic fabricated the backplane with commercial FR408 to enable solid performance even at high signal frequencies. While maintaining backward compatibility with legacy VME technology via preservation of the VMEbus 6U mechanical form factor and through-mapping of the current VMEbus signals to the VITA 46 connectors, the VITA 46 technology brings the these features to reality while maintaining the ability to operate together with existing VME technology boards.
