RTG001 - USB 主板連接1.5百萬FPGA system,資料擷取與信號處理(包含高速的A/DD/A)

data acquisition & processing system

  • User programmable Xilinx XC2V1500-6 FPGA.
  • 2 channels of 210Mhz 12 bit A/D
  • 2 single ended (optionally differential) channels of 160Mhz 16 bit D/A
  • 8 bits digital I/O
  • Hi Speed (480Mbits/sec) USB 2.0 connection to a host PC.
  • Can be used as a stand alone board for embedded systems.
  • FPGA can be configured via USB, Xilinx JTAG cable or from on-board PROM
  • Single 5V power supply required ?20W mains Power Supply Unit included
    Host API supported for Windows 2000 and XP and Linux FPGA and DSP loading, resetting and data exchange all performed with simple to use software interface.
  • Optional expansion via HERON module slot

  The fast A/D and D/A channels are directly connected to the user programmable FPGA, allowing data to be processed by a user FPGA program. The FPGA can be used to perform digital processing between the analogue inputs and outputs, or the data can be passed to and from a PC using the USB 2.0 connection and provided software.

The USB connection is supported via the 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 .
  • Analogue I/P
    2 differential input channels with common or independent clocking set by jumper
    Standard Input characteristics:
    +/-0.768mV differential inputs each on 2 MMT co-axial connectors (U.FL if you choose the differential output option)
    A/C coupled 50R, signal B/W from 200Hz to 450Mhz
    Zero input noise typically 3 levels maximum 8 levels
    Offset typically +-3 levels maximum +-8 levels
    Optional Input types:
    D/C
    D/C coupled 50R - Signal B/W 0hz to 450Mhz but each input must not exceed the range 0v to +3.3V (of this module). This means a 2.8V DC offset is required.
    Zero input noise typically 3 levels maximum 10 levels
    Offset typically +-8 levels maximum +-16 levels
  • Analogue O/P specifications
    Standard Output characteristics:
    2 single ended channels with independent clocking
    +/-0.374V single ended output on MMT co-axial connector
    A/C coupled 50R, signal B/W from 725Hz to 200Mhz
    Optional Output types:
    D/C 50R, signal B/W 0 ?200Mhz
    Differential
    +/-2.1V differential, on a pair of U.FL co-axial connectors per channel
    A/C coupled 50R, signal B/W from 750Hz to 145Mhz
    D/C coupled 50R, signal B/W from DC to 145Mhz
