Overview
The VPXI enclosure
is a six-slot system for 3U VPX cards that provides a performance
architecture for instrumentation, signal processing and embedded
computing applications. The VPXI system provides multiple, high
performance data planes employing both centralized and ring
topologies. Slot 6 provides an IO slot for system IO and is not
integrated in the communications planes.
The VPXI Expansion chassis has a x8 Cabled PCI Express
connection to the host, supporting >1GB/s sustained data rates
with X6 and X5 series cards. The chassis has an integrated PCI
Express packet switch that supports 5 slots (x8, x4, x4, x1, x1
lanes, Gen2).
The system also supports private communications between cards
using private links constituting two data planes. A centralized
data plane to slot 1 is provided with a x1 lane to each slot. The
second plane has a ring topology using x2 lane connections so that
each lot is connected to all others.
Integrated timing and triggering features support
instrumentation and signal processing applications that require
low noise, high performance clock and trigger features. Each
peripheral slot receives a dedicated clock and trigger input, as
well as lower speed coordination signals. These signals are used
by VPX-COP, X6 and X3 IO card families and support simultaneous
and coordinated sampling.
The VPXI enclosure integrates a 500W power supply. Upper and
lower fan assemblies provide forced air cooling for all cards.
