VITA 57.1 recognized by ANSI, new standards brew
An update on VITA's burgeoning standards, including VITA 40 and 59, plus the newly incarnated VITA 60 and 62, among others.
VSO ANSI accreditation
Accredited as a Standards Development Organization (SDO) in June 1993 by the American National Standards Institute (ANSI), the VITA Standards Organization (VSO) meets every two months to address vital embedded bus and board industry standards issues. Information on ANSI/VITA standards is available on the VITA website at www.vita.com.
VSO study and working group activities
Standards within the VSO may be initiated by a study group and developed by a working group. A study group requires the sponsorship of only one VSO member and is used to build interest in a standard. A working group requires the sponsorship of at least three VITA members, and the proposed work must fit within the defined scope of VITA's accreditation with ANSI.
ANSI/VITA 40-200x, Status Indicator
Objective: Standardize front-panel indicators ‚Äì revisions to ANSI/VITA 40-2003.
Status: Craig Hartley reported on efforts to revise the ANSI/VITA 40, Status Indicator standard and discussed efforts to make the standard better known to others creating status standards for other devices.
VITA 51.2, Physics of Failure Reliability Predictions
Objective: This effort will look at the physics of failure as it relates to ANSI/VITA 51.0 and 51.1.
Status: Lori Bechtold reviewed the development of 51.0 and 51.1 and CRANE's effort to update MIL-HDBK-217. She proposed the formation of VITA 51.2, Physics of Failure Reliability Predictions. A signup list was distributed. Lori plans a full-day working group meeting at the November VSO meeting.
VITA 57.1, FPGA I/O Mezzanine Pin Assignments
Objective: To define a standard mezzanine connector, form factor, and pin assignment strategy optimized for connecting I/O to FPGAs.
Status: John Rynearson reported on VITA 57 for Malachy Devlin, who could not attend the meeting. 57.1 has been recognized by ANSI. A marketing activity to promote 57.1 is being planned. The working group is working on 57.2 and 57.3.
VITA 59, RSE: Rugged System-On-Module Express
Objective: To develop a standard for a small form factor module used in applications that require ruggedized form factors.
Status: Manfred Schmitz reported on VITA 59. The first draft has been completed. A second round of revisions should be completed by October.
VITA 60, Alternative Connector on VPX
Objective: Develop an alternative connector for VPX that is PCB compatible, but not mechanically interoperable with the current standard.
Status: Colleen Murphy reported on the status of Amphenol's efforts to develop an alternative connector for VITA 46 modules. A signup list was distributed to start a working group. The effort will be known as VITA 60.
VITA 61, XMC with Alternative Connector
Objective: Develop an alternative connector for XMC that is PCB compatible, but not mechanically interoperable with the current standard.
Status: Greg Powers, Tyco, reported on the development status of an alternative connector for XMC. The design is complete. Currently work is progressing on modeling, and empirical testing will follow.
VITA 62, Power Supply Modules
Objective: Develop a standard for modular power supplies.
Status: Sean Lorimer reviewed a proposal to develop a plug-in power supply standard for embedded applications. A signup list was circulated to start a working group. This effort will be known as VITA 62.
