Call for Consensus Body Members to Reaffirm ANSI/VITA 68.0 and 68.1-2017 as reaffirmed standards

Tuesday, December 20, 2022 9:57 AM | Dean Holman (Administrator)

VITA is accepting registrations to be a member of a public review VITA Consensus Body for voting to reaffirm these two standards. You do not have to be a VITA member to participate in this Consensus Body.  VITA members with active Workspace profiles should sign up in Workspace.

VITA Members can sign up for free (while logged into their account) while non-members must pay a nominal fee to participate. The response deadline to register for this consensus body is: January 4, 2023.

Reaffirmation of Approved Standard

Under ANSI/VITA rules, every 5 years an approved standard must be reaffirmed, revised, or withdrawn.  The VSO by ballot feels that the following standard continues to be relevant to our community and is free from significant errors. Therefore, the VSO by ballot has recommended that this standard be reaffirmed.

Consensus body registration for voting on reaffirmation of these two standards is now open.

ANSI/VITA 68.0-2017 - VPX Compliance Channel Standard
Abstract: VITA 68.0 is the Base Standard of the VITA 68.x family of standards for signal integrity compliance of VPX systems and components. This standard provides an overview of the VITA 68.x family of standards and defines common requirements for VPX modules and VPX backplanes that apply across the range of VITA 68.x standards.

ANSI/VITA 68.1-2017 - VPX Compliance Channel - Fixed Signal Integrity Budget Standard
Abstract: The ANSI/VITA 68.1-2017 standard defines a VPX compliance channel fixed signal Integrity budget including module performance criteria and common backplane performance criteria required to support multiple fabric types across a range of defined baud rates. This allows backplane developers to design a VITA 68.1 compliant backplane that supports required bit error rates (BER) for multiple fabric types when used with modules that are compliant to VITA 68.1 budget criteria. This also allows module developers to design VITA 68.1 compliant Plug-In Modules that are interoperable with other VITA 68.1 compliant modules when used with a VITA 68.1 compliant backplane. VITA 68.1 defines a single budget encompassing modules and backplanes at various baud rates, with a "large system budget" that supports interoperability of VITA 68.1 compliant modules with any VITA 68.1 compliant backplane, including large slot count backplanes with relatively long traces.  VITA 68.1 is part of the VITA 68.x family of standards for signal integrity compliance of VPX systems and components. Please refer to VITA 68.0 for an overview of the VITA 68.x family of standards.

How to Apply for the Consensus Body

  • User-Industrial/Commercial: An appropriate participant is using this standard in an industrial or commercial application
  • User-Government/Military: An appropriate participant is a representative of a government agency using this standard in a government or military application.
  • Research: An appropriate participant is involved in research or consulting that may use this standard.
  • General Interest: An appropriate participant is an interested party not necessarily involved in producing, directly using, or acquiring product using this standard.

Please note that company membership in VITA is NOT a requirement to join this consensus body. This registration is open to both VITA members and non-members. You must register via this form if you wish to participate in the upcoming ballot. VITA Members can sign up for free (while logged into their account) while non-members must pay a nominal fee to participate.

In the case that you believe this standard needs a revision, please indicate so in the comments field of the registration form and be prepared to sponsor and actively participate in the revision effort. If you are selected for the consensus body, you may provide minor editorial comments during the balloting.

Please register ONLY IF you intend to vote.
