The VPXI enclosure is a five-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 1.2 GB/s for X5-series and 3.4 GB/s for X6-series cards. The chassis has an integrated PCI Express packet switch that supports 4 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 350W power supply. Upper and lower fan assemblies provide forced air cooling for all cards.
