VTX951

The VTX951 is a 1U Open VPX chassis with two 3U VPX payload slots. It can accept 0.8-inch, 0.85-inch and 1.0-inch pitch modules and is ideal for commercial deployment. The Chassis incorporates a VadaTech third generation shelf manager that provides tier 2 health management. The VTX951 can accept convection cooled modules in VITA 48 pitch. A layer 2 GbE switch supports 802.1D Spanning Tree Protocol, 802.1W Rapid Spanning Tree, 802.1s Multiple VLAN Spanning Tree, programmable per-port VLAN configurations, 802.1Q, etc. The switch supports IEEE1588V2 and has two ports to each of the VPX modules and two ports to the front of the chassis via RJ-45. The module accepts GPS antenna input or other clocking options as input/output to the chassis and generation of any clock frequency to the backplane for the VPX modules clock references.

Intel E-2176M (Coffee Lake)

The Intel® Xeon® Processor W-11865MRE (Tiger Lake-H) with 8 cores. The processor base frequency is 2.6 GHz with max turbo frequency of 4.7 GHz. The Intel CPU interfaces to each of the VPX modules via x8 PCIe Gen4. It also provides dual 10GbE to the front panel. The VTX951 has 32 GB of DDR4 memory with ECC, 2TB of NVMe M.2 removable storage and 64GbE of SSD on board. The BIOS allows booting from the NVMe module, PXE boot as well as USB. There are dual USB 3.0 type C connectors for extended storage or peripherals.

JTAG Master/JTAG via Ethernet Virtual Probe

The VTX951 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. 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 without the need to install additional JTAG equipment on-site.

Power Supplies

The VTX951 has a 500W AC universal input power supply that provides 100W per slot.

Cooling and Temperature Sensors

The VTX951 is designed to meet the ANSI/VITA 65 standard. It provides right to left push/pull cooling (18 CFM per payload slot at 0.24 in-H2O @ 5000 feet) to the VPX payload and RTM slots. The Chassis has a removable Air Filter at the front. The module provides cooling to the RTM.

Backplane

The backplane provides two 3U VPX payload slots in a star configuration, fully compliant to VITA 46.0 baseline specification, with additional support to the RTMs, compliant to VITA 46.10 and OpenVPX VITA 65. VadaTech is open to modify the backplane to meet customer requirements.
