Open VPX rackmount chassis has payload options

Designed with two 3U payload slots, the VTX955 is a 1U Open VPX chassis from VadaTech. The chassis can accept 0.8, 0.85-inch and 1.0-inch (20, 21.5 and 25.4mm) pitch modules and is designed for commercial deployment.

A 500W AC universal input power supply supports 90W AC per slot and the chassis has left to right push/pull cooling to the VPX payload and rear transition module (RTM) slots. The VTX955 is designed to meet ANSI/VITA 65 (18 CFM per payload slot at 0.24 in-H2O at 5,000 feet). The shassis incorporates a VadaTech third generation shelf manager that provides tier 2 health management. There is a layer-two GbE switch which supports 802.1D spanning tree protocol, 802.1W rapid spanning tree, 802.1s multiple VLAN spanning tree and programmable per-port VLAN configurations. The switch also has two ports to each of the VPX modules as well as having four ports to the front of the chassis via RJ-45. The module accepts GPS or other clocking options as I/O to the chassis and generation of any clock frequency to the backplane for the VPX modules clock references.

The VTX955 provides JTAG master capability. Data streams sent out via the chassis JTAG switch module (JSM) configure arbitrary JTAG slave devices on VPX cards. Virtual probe services are available as an option to provide JTAG via Ethernet for Xilinx FPGAs. This allows for standard development tools such as Xilinx iMPACT/ChipScope to treat the switch/JSM combination as if it were a standard JTAG probe, says the company. This approach frees the developer from having to attach JTAG probes directly to the VPX module or JSM which can be difficult when systems are already fully assembled. It also allows for remote debugging across long distances when required without the need to install additional JTAG equipment on-site.

VadaTech provides innovative embedded computing solutions from board-level products, chassis-level platforms, to configurable application-ready systems. With a focus on AdvancedTCA, MicroTCA, VPX and PCIe solutions, the company offers electrical, mechanical, software, and system-level expertise, to provide customised commercial or rugged computing to meet the most complex customer requirements. VadaTech also offers specialised product solutions for VME, CompactPCI, and other architectures. It is a member of PICMG and VITA.
