VITA
41 - VXS Backplane Introduction
VITA (VME International Trade Association) is continually striving
to maintain VME's strength in the embedded computing industry
by upgrading the technology. VITA 41 is the newest standard
and the first entry of a VME standard into switched fabric technology.
It's based on the VME64 Extensions standard with a high-speed
connector taking place of P0 in the payload slots. The switch
slots do not use the VME64X boards. The slots are made up of
high-speed connectors and a bladed power connector. The form
factor and the VME bus remain the same. Switched fabric pinouts
and protocols are defined in complimentary standards. So far,
41.1 specifies Infiniband and 41.2 is for Rapid IO with others
such as StarFabric planned for the near future. (-More-)

The
VITA 31.1 specification for Gigabit Ethernet over VME64x
and VITA 41.0 core specification for the VXS Backplane
have been ratified. However, there are some proposed changes
to update VITA 41 to have it go to VITA 41.1.1. They are
considering making modifications to allow conduction cooling
and allow more room for PMC modules on the switch cards.

News |
|
CompactTCA has been announced, which retains compatibility with most
existing CompactPCI/PICMG 2.16/2.17 products. Combining
several CompactPCI specifications into a single standard,
it ensures interoperability and the high availability
and scalability attributes of packet-switched technology
in the proven, lower cost CompactPCI/PICMG 2.16 form factor.

New
Products
5-slot
Mesh AdvancedTCA Backplane
The 5-slot Mesh ATCA backplane is compliant to PICMG 3.0 Rev. 1.0
specifications. It is actually a Replicated Mesh, however, standard
Mesh or Dual Star configurations are implementable.
CompactPCI
Rear Extender
The card allows rear I/O signals to be extended outside the chassis
for prototyping and testing. It comes in a 6U x 180mm form factor
and features a 12-layer stripline design.

Coming
Soon
VXS Backplanes
The VXS Backplanes will be compliant to VITA 41 specifications. Versions
in Dual Star and Single Star topologies will be available. Replicated
Single Star versions are another possibility. Contact Bustronic for
more details. |
