Overview
The X6-GSPS integrates high-speed digitizing with signal processing on
a PMC/XMC IO module for demanding DSP applications. The tight coupling of
the digitizing to the Virtex6 FPGA core realizes architectures for SDR,
RADAR, and LIDAR front end sensor digitizing and processing. The PCI
Express system interface sustains transfer rates over 2 GB/s for data
recording and integration as part of a high performance realtime system.
The X6-GSPS features two, 12-bit 1.8 GSPS ADCs that can be interleaved
to use as one 3.6 GSPS digitizer. Analog input bandwidth of over 2.5 GHz
supports wideband applications and undersampling. The sample clock is from
either a low-jitter PLL or external input. Multiple cards can be
synchronized for sampling and down-conversion.
A Xilinx Virtex6 SX315T (LX240T and SX475T options) with 4 banks of 1GB
DRAM provide a very high performance DSP core with over 2000 MACs
(SX315T). The close integration of the analog IO, memory and host
interface with the FPGA enables real-time signal processing at extremely
high rates.
The X6-GSPS power consumption is 20W for typical operation. The module
may be conduction cooled using VITA20 standard and a heat spreading plate.
Ruggedization levels for wide-temperature operation from -40 to +85C
operation and 0.1 g2/Hz vibration. Conformal coating is available.
The FPGA logic can be fully customized using VHDL and MATLAB using the
Frame Work 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.
