Curtiss-Wright’s Rugged, Pre-Architected, Mission-Specific Computer System Targets SDR, EW Applications

Curtiss-Wright has just introduced the first member in a new family of rugged, pre-integrated, mission-specific management computer systems based on its line of COTS modules. This first family member targets SDR (software-defined radio) and EW (electronic warfare applications) and so it packs as many as four of the company’s VPX3-530 High-Speed Transceiver modules with either four 12-bit, 2Gsamples/sec or two 12-bit, 4Gsamples/sec ADCs and two 14-bit, 2.8Gsamples/sec (5.6Gsamples/sec with interpolation) DACs controlled by a Xilinx Virtex-7 690T FPGA that also provides user-programmable, real-time signal processing. An Intel-based processor board, clock generator module, and power supply complete the system’s electronic hardware complement and all modules are housed in a rugged MPMC-9354 chassis that looks like this:

The system is fully qualified to MIL-STD-704F, MIL-STD-810, and MIL-STD-461 testing.


Here’s what the inside of the chassis looks like:

The VPX3-530 High-Speed Transceiver module supports phase-coherent ADC sampling and DAC output across multiple cards when used with the XCLK1 synchronous clock source. Here’s a photo of the VPX-530 module, prominently showing the Virtex-7 690T FPGA:

And here’s a block diagram of the VPX3-530 module showing the FPGA, ADCs, DACs, and the module’s two banks of DDR3 SDRAM:

The digital section is essentially the Virtex-7 FPGA, which implement’s all of the module’s logic, the SDRAM, and the non-volatile memory.
