X6-250M Data Acquisition Board with LTC2157-14 ADCs and Virtex6 FPGA all on XMC
The X6-250M Data Acquisition Board with FPGA integrates digitizing with signal processing on a PMC/XMC IO module. The module has a powerful Xilinx Virtex 6 FPGA signal processing core, and high performance PCI Express/PCI host interface. Applications include software-defined radio, RADAR receivers, and multi-channel data recorders.
The X6-250M has eight simultaneously sampling A/D (LTC 2157-14) channels that sample at rates up to 250 MSPS (14-bit). The A/D have matched input delays and response. The board is available as either AC or DC coupled inputs. The AC variant has an input bandwidth of upto 400MHz, the DC variant has an input bandwidth of up to 550MHz. The A/D are supported by a programmable sample clock PLL and triggering that support multi-card synchronization for large scale systems.
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 X6-250M has both XMC and PCI interfaces, supporting PCI Express or older PCI systems. The PCI Express interface provides up to 2 GB/s sustained transfers rates through a x8 PCIe Gen2 interface.
System expansion is supported using secondary PCI Express or Aurora port used as a private data channel or second system bus.
The X6-250M power consumption is 18W 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 and 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 and DSP functions such as 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.
