X3-DIO Data Acquisition Board with 64/32 bit LVTTL/LVDS and FPGA
The X3-DIO is an XMC IO module that can be fitted in a PC using a XMC to PCIe adapter or XMC to PCI adapter or a CompactPCI chassis using a XMC to CompactPCI adapter or a Standalone PC. Other hosting options include a standalone eInstrument and connection to a variety of PC hosts.
The X3-DIO is for high speed digital IO data interfaces featuring 64bits of front-panel digital IO. The DIO is either single-ended LVCMOS or LVDS differential pairs. The DIO is directly connected to the FPGA, supporting high speed pattern generation, digital recording, custom IO interfaces and control applications.
Flexible trigger methods include counted frames, software triggering and external triggering. The sample rate clock is either an external clock or on-board programmable PLL clock source.
Data acquisition control, signal processing, buffering, and system interface functions are implemented in a Xilinx Spartan3A DSP, 1.8M gate device. Two 512kx32 memories are used for data buffering and FPGA computing memory.
The logic can be fully customized using VHDL and MATLAB using the FrameWork Logic toolset. The MATLAB BSP supports real-time hardware-in-the-loop development using the graphical, block diagram Simulink environment with Xilinx System Generator.
The PCI Express 4 lane interface supports continuous data rates up to 220 MB/ s between the module and the host. A flexible data packet system implemented over the PCIe interface provides both high data rates to the host that is readily expandable for custom applications.
