20、Advanced Module Format for VMEbus systems, an evolutionary step forward for the provision of high-speed interconnects in harsh-environment applications. Foreword VME has been the de-facto bus standard for Commercial off the Shelf ( COTS ) Circuit Card Asemblies since the 1980s. VME boards have prove
21、n to be remarkably capable of evolving to support newer technologies with innovations such as VME Subsystem Bus, PCI Mezanine Cards (PMCs) and VME320. However, advances in technologies, appearing particularly in interconnects, have demonstrated the need for an advance in system development. This adv
22、ance needs to acommodate high speed interconnect, particularly serial interconnects, and higher power delivery in concert with beter heat removal. This draft standard addreses these needs in the context of IEE 1101 form factor modules. Other specifications may addres alternate outlines, such as VITA
23、-48 (Draft). Because electronics miniaturization is driving the plug-in module I/O count, most system interconnects wil need: Multi-gigabit diferential technology Core computing cluster switched fabrics Serial RapidIO, PCI Expres, Advanced Switching Interconnect Sufficient ports to enable distribute

45、2 (for air cooled and conduction cooled plug-in modules, respectively). These features are evident in the mechanical drawings provided. The VITA 46 base standard defines physical features that enable high-speed communication in a compliant system. These features include: a 6U by 160mm by 4HP Eurocar
46、d format board with high speed diferential connectors, a 6U by 160m by 4HP Eurocard format board with a combination of high speed diferential and single-ended connectors, and the backplane/chasis infrastructure needed to support these features. The base standard also defines similar physical feature
47、s for 3U by 160mm by 4HP Eurocard format, providing the same two types of connector options discussed above for 6U plug-in modules. Many features caled for in the base specification wil be compatible with the requirements of other standards, such as VITA-48 draft, but this standard concerns only the
48、 IEE 1101 compatible applications. This base standard also defines alignment and keying features used to protect the connector system. The base standard does not addres the possible serial fabric configurations available in systems which utilize the standard. While the base standard does not addres
49、the use of ANSI/VITA-1.1 or VITA-41 plug-in modules, or modules which are constructed to the mechanical requirements of VITA-48, chasis and backplanes can be constructed which provide compatibility with plug-in modules built to these standards. The dot specifications alow the use of the single-ended connector alocation for paralel busses, such as VME or PCI, completing the compatibility betwen older standards and this one. 1.3 Terminology 1.3.1 Specification Key Words Do not specify or claim conform
