9.1 VPX Connectors

Publication No. SBC330-0HH/3
SBC330 is a 3U board and uses differential‐type VPX connector modules for P2.
Figure 9-1 SBC330 Connector Layout
VPX connectors are idealized such that they provide a means of dealing with
high‐speed differential pairs, for high speed fabric communications. The
connectors use wafers of PCB material that maintain the characteristic impedance
of the trace through the connector interface. Also, by geographical arrangement
each pair is completely shielded left, right, top and bottom from the next signal
pair.
VPX connectors may appear less robust than previous industrial connectors, but
their construction means that actually they are more robust; they cannot suffer
from pins bending to create shorts and the multiple contact solution results in
high reliability in high vibration environments.
The P0 pin out is completely defined by the VPX 46.0 Specification.

The Rear Transition Module for the SBC330 is the SBC330RTM. It provides accessibility to the
backplane signals and a means for connecting to other equipment – see
Manual for more details.
