Where is VITA 100 Now and Where is It Headed? (Part 3)
What you’ll learn:
- What is VITA 100?
- What standards are available now?
- What related standards will be coming in the future?
This video is part 3 of the VITA Basics webinar that you can watch in its entirety.
VITA 100 is a set of VITA standards that extend VPX standards with higher-speed features as well as improve the flexibility and performance of the design environment. Most of the base standards are in draft mode and will be voted on in the near future. These will be moved to ANSI standards in 2026.
Compatible hardware will be available in 2026 as the standards are finalized. Most will be used initially for test and evaluation systems. Given the usual lead times for defense and avionics systems, production systems based on VITA 100 are a year or more away.
In the video above, I talk with Daniel Toohey, Toohey is a Fellow Chief Technologist within the Advanced Concepts Group at Mercury Systems, Michael Walmsley, Global Product Manager in the Aerospace, Defense and Marine business unit at TE Connectivity, and Mark Littlefield, Senior Manager of Embedded Computing Products and Services for Elma Electronic about where VITA 100 is now and where it is headed.
The roadmap for VITA 100 (Fig. 1) is extensive and will include a number of additional standards. Many extend existing VITA standards and VITA 100-based systems will also employ other VITA standards, such as VITA 46.11 System Management, which is a recent addition as well.
Most of the basic mechanical and electrical standards will be ready by 2026 but some, like the rear transition module (RTM) is still a work in progress. The same is true for air-flow-through (AFT), liquid-flow-through (LFT) and conduction-cooling options. These need to address the higher power and cooling requirements as well as the new 4U form factor (Fig. 2).
