Approved November 2010
American National Standards Institute, Inc.
American Approval of an American National Standard requires verification
by ANSI that the requirements for due process, consensus, and
National other criteria for approval have been met by the standards
developer.
Standard
Consensus is established when, in the judgment of the ANSI Board
of Standards Review, substantial agreement has been reached by
directly and materially affected interests. Substantial agreement
means much more than a simple majority, but not necessarily
unanimity. Consensus requires that all views and objections be
considered, and that a concerted effort be made toward their
resolution.

The use of American National Standards is completely voluntary;
their existence does not in any respect preclude anyone, whether
he has approved the standards or not, from manufacturing,
marketing, purchasing, or using products, processes, or procedures
not conforming to the standards.
The American National Standards Institute does not develop
standards and will in no circumstances give an interpretation of
any American National Standard. Moreover, no person shall have
the right or authority to issue an interpretation of an American
National Standard in the name of the American National Standard
Institute. Requests for interpretations should be addressed to the
secretariat or sponsor whose name appears on the title page of this
standard.

CAUTION NOTICE: This American National Standard may be
revised or withdrawn at any time. The procedures of the American
National Standards Institute require that action be taken
periodically to reaffirm, revise, or withdraw this standard.
Purchases of American National Standards may receive current
information on all standard by calling or writing the American
National Standards Institute.

Abstract

This VITA 46 (VPX) subsidiary standard defines PMC or XMC mezzanine rear I/O pin
mappings to VITA 46.0 plug-in module backplane connectors.

Foreword

The VITA 46 standard defines plug-in modules, backplanes, and chassis assemblies that
are structured to support high-speed serial interconnect among boards in a system and to
support plug-in modules with higher power loads and more effective thermal relief.
These definitions are based on the IEEE 1101 Euroboard definitions and are a logical
evolution of the VME board definitions.

This standard augments the basic form factor and assembly definition in the VITA 46.0
standard by adding wiring definitions to extend rear I/O ports on mezzanines on a plug-in
module to that module’s backplane connector(s).

VITA 46.9 Working Group Members

Developing a standard is often a long and tedious process. Many working group
members put in a full day of work at their regular “day” job while participating in the
development of a VITA standard. Much thanks are extended to the various participants
of the VITA 46 working group for their time and effort put forth in the development of
VITA 46.9.

VITA 46.9 Draft Editors

While straight forward in concept, creating VITA 46.9 was not simple in development.
VITA 46.9 had four different draft editors. Each provided their own particular expertise
before handing the duties off to the next draft editor when they relinquished their position
usually due to a new assignment within their current company or to pursue a new
opportunity with a different company.

As VITA’s technical director, I would like to thank each draft editor for their work and
hard effort in making VITA 46.9 a recognized American National Standard.

Ken Boyette, Critia Computer, Inc.
Jing Kwok, CWCEC
Chris Eckert, GE Intelligent Platforms Embedded Systems

With special thanks going to Jim Goldenberg, GE, the present 46.9 draft editor for
his efforts in finishing the draft and bringing it to ANSI recognition.

1 Introduction (Normative)
The VITA 46 (VPX) family of standards defines plug-in modules, backplanes, and host
chassis assemblies that build upon the utility of the IEEE 1101 Euroboard form factor by
providing a series of high-speed fabric capable backplane connectors in lieu of the
conventional pin and socket connectors.

This VITA 46.9 standard defines connector and pin mappings to support rear I/O port
wiring for single-width PMC and XMC mezzanine cards on 3U and 6U VPX plug-in
modules.

1.1 Overview
VPX plug-in modules might include IEEE 1386.1 PMC and or VITA 42 XMC
mezzanine card installation sites for the addition of application-specific functions. These
mezzanine modules can include single-ended and or differential pair rear access ports on
carrier connectors Jn4 or Jn6.

The Jn4 connector has 64 single-ended contacts, in two columns of 32. These contacts
are capable of supporting interfaces ranging from dc logic to 1000BaseT Ethernet. This
connector can be utilized by either a PMC or a XMC mezzanine module. The Jn6
connector comprises 20 differential pairs, 38 single-ended contacts, in six columns of 19,
plus ground contacts to support high-speed differential signals and is used on XMC
mezzanine modules.

A 3U VPX carrier is capable of hosting one single-width PMC or XMC mezzanine
module, and has the following general options for backplane pin field assignments to
support rear I/O access for the mezzanine module:

Figure 1.1-1: 3U VPX Carrier Pin Field Options

Similarly, a 6U VPX carrier is capable of hosting either one or two single-width PMC or
XMC mezzanine modules, and has the following general options for backplane pin field
assignments to support rear I/O access for each mezzanine module:

Figure 1.1-2: 6U VPX Carrier Pin Field Options

In this standard, pin field combinations are named according to how the element pin
fields are distributed on the backplane connectors. For example:
P3w1-P64s+ P4w1-X12d+X8d defines the composite pin field containing:
- one P64s pattern map for 64 single-ended contacts on the PMC-Jn4 connector
- one X12d pattern map for differential pairs on XMC-Jn6 rows 5, 7, 9, 15, 17, and 19
- one X8d pattern map for differential pairs on XMC-Jn6 rows 1, 3, 11, and 13
- The first pattern after the hyphen, P64s, is mapped to the P3 connector starting at
wafer 1, following in order the X12d pattern is mapped to the next available pins,
in this case, to the P4 connector starting at wafer 1, and then on to X8d pattern
mapped to the P4 connector starting at wafer 7. This example is the left-most pin
field shown in Figure 1.1-2 above.
