Catalog C-035 Rev. C
Today, some customer applications have requirements for high bandwidth transfer between VMEbus cards. Requirements
which even the most updated VME parallel bus cannot support. To meet this need the VITA 41 specification has been developed.
VITA 41 VXS (VME Switched Serial) defines a common data plane interconnect using switched serial topologies.
Positronic’s VPX
power connector was
developed
to support
VITA 41.
The
VPX series
provides a dedicated power interface
between boards and backplanes eliminating the need to use valuable high speed contacts to carry power.
The
VPX series
has a unique package size which allows compatibility with conduction cooled boards per IEEE 1101.2.
A unique size, multiple power contacts, three levels of sequential mating and high reliability make the
VPX series
suitable for
VITA 41 or any similar application.
