A new XMC module integrates high-speed digitizing and signal generation with signal processing on a PMC/XMC I/O module for demanding DSP applications. The tight coupling of analog I/O to the Virtex-6 FPGA core dramatically simplifies SDR, RADAR and LIDAR implementations. The X6-1000M from Innovative Integration uses a PCI Express interface that sustains transfer rates over 2.8 Gbyte/s for data recording applications and integration within real-time systems.

The X6-1000M features two 12-bit 1 Gsample/s A/Ds and four 16-bit 1 Gsample/s DACs. Analog input bandwidth of over 2 GHz supports wideband applications and RF under sampling. The DACs have features for interpolation and coarse mixing for up conversion. The onboard, low-jitter PLL or an external input may drive the sample clock. Multiple cards are guaranteed to start and process synchronously for sampling and down-conversion.

A Xilinx Virtex-6 SX315T (LX240T and SX475T options) with four banks of 1 Gbyte DRAM provides a very high-performance DSP core with over 2000 MACs (SX315T). The close integration of the analog I/O, memory and host interface with the FPGA enables real-time signal processing at extremely high rates. The X6-1000M power consumption is 19W for typical operation. The module may be conduction cooled using VITA20 standard and a heat spreader. Ruggedization options for wide-temperature operation from -40° to +85°C operation and 0.1 g2/Hz vibration.

The FPGA logic can be fully customized using VHDL and MATLAB using the FrameWork Logic tool set. The MATLAB BSP supports real-time hardware-in-the-loop development using the graphical block diagram Simulink environment with Xilinx System Generator. IP cores for many wireless, DSP and RADAR functions such as large-scale preintegrator, DDC, PSK/FSK demod, OFDM receiver, correlators and large FFT are available. Software tools for host development include C++ libraries and drivers for Windows, Linux and VxWorks. Application examples demonstrating the module features are provided.
