Providing a progress update, VITA 100 chair Steve Devore (pictured), described it is a continuation of VPX, supporting evolving power and data processing demands. One requirement is to double the density of today’s VPX connectors while maintaining the maximum current connector length. The VITA 100 study group has selected TE Connectivity’s MultiGig HD connector, citing doubled pin count, data rates of 100Gbit per second, increased current capacity and suitability in rugged environments.
“Selection as the VITA standard . . . is the culmination of two years of dedicated research and development by our innovative cross-functional team,” said Michael Walmsley, senior project manager at TE Connectivity.
VITA 100 will also be required to support higher speed protocols, including 100G Ethernet per lane and PCIe Gen 6. “Today, 400GbE can be supported but this is expected to increase to 1.6TbE,” said Devore, explaining the reason why the standard was needed.
As processing increases, more power is needed and this brings its own set of problems, said Devore. The standard definition will also increase the power capacity of VPX to above 500W.
Backwards compatibility is important, Devore said, speaking at Embedded Tech Trends 2025. The standard will enhance interoperability by minimising the number of slot profiles, he said, keeping the network but upgrading the backplane.
