The RTG002 is a self contained programmable digital I/O system. It can be used stand alone or connected to a PC via the USB 2.0 connection.

The FPGA I/Os are directly connected to the Digital I/O connectors. This allows the FPGA design to use them as Single ended or differential signals with any mix of inputs and outputs. For LVDS differential inputs termination resistors must be fitted at build time, so you need to specify how many LVDS inputs you will use when you order your system.

Several FPGA designs are provided as starting points for your FPGA design, offering different mixes of inputs and outputs.

The Virtex^®-II FPGA can be programmed to provide logic or data processing functions according to your needs.

The USB connection is supported via the HUNT ENGINEERING Host-API software. This allows software applications and tools on the Host PC to access the hardware using a consistent software interface without the need to understand or program the hardware or USB directly.

The FPGA program can be loaded over the USB connection using a software tool that directly accepts the output from development tools for the Xilinx^® FPGA. Alternatively a Xilinx^® JTAG cable (Parallel or USB) can be used to load the FPGA and or program the on board configuration PROM.

The FIFO connections can be used to stream data to or from a module in the system. They are capable of up to 50Mbytes/second in each direction, but the Host PC, its USB controller and the operating system will all impose their own limits to this speed.

The system is delivered ready to go with a power supply (requires an IEC lead specific to your country), USB cable, I/O cables and a CD with all of your documentation, software tools and examples. The only other thing you need are development tools for the Xilinx^® FPGA, for example Xilinx Foundation ISE^® from www.xilinx.com .

Technical Specification

• FPGA

  Xilinx 1M gate Virtex^®-II FPGA, speed grade 4. XC2V1000-4FG456.
  With no heatsink fitted (standard) the FPGA can dissipate 2.4 Watts at 50deg C ambient temperature.
  The power circuits are capable of delivering more than this, so a heatsink may be required for your design.
  If that is the case a larger 5V Power Supply Unit may also be necessary

• Host Bus

  USB 2.0 capable of up to 50Mbytes/second dependent on host PC and USB configuration.

• Maximum Dimensions:

  160mm x 110mm x 21mm.

• Power requirements

  5V Max: 1.55A plus the power taken by the FPGA. Typ: 1.15A plus FPGA
  The Mains Power Supply Unit included can supply up to 4A, which is enough to power an FPGA design that is less than the 2.4W bare package maximum dissipation.
