VITA's Jerry Gipper outlines the latest trends in open-systems standards for rugged embedded computing
OKLAHOMA CITY – Embedded computing standards are still being developed, and new products and design wins are being announced at a normal pace. Electronic Design magazine reports Continue reading original article
27 Jan. 2021 -- Members of the VITA open standards, open markets trade association were able to get eight open-systems standards through the VITA/ANSI process in 2020, including ANSI/VITA 46.30 and VITA 46.31, which enabled extending the data rate of VPX to the next level of at least 25 gigabaud for protocols such as 100GBASE-KR4 Ethernet and PCI Express Gen 4.
The higher-data-rate connectors defined in these standards are intermateable to legacy VITA 46.0 connectors and follow the same form factor. The working groups have been focused on this problem for several years.
Other trends in 2020 involved the release of additional ANSI/VITA 67 coaxial interconnect on VPX standards. These standards enable various configurations to support RF connections to a VPX module, extending the use to some interesting applications utilizing RF I/O. This work complements the configurations defined under various VITA 66 VPX optical standards.
