Digital Intermediate Frequency (DIF) Receiver Board

Digital Intermediate Frequency (DIF) Receiver Board is a FPGA based high speed data acquisition board. High speed ADCs are used for digitization of analog IF signals and Virtex-5 series FPGAs for front-end digital signal processing and data streaming over high speed links. The board receives four channel analog signals for digitization. The required timing signals are fed from radar timing and IO generation board. FPGA based solution is implemented to meet the functional requirements of the board.

The DIF receiver board finds application in multiple airborne radar platforms:

  • Exciter Receiver Processor
  • Radar Processing Unit

KEY FEATURES

  • Data acquisition and signal processing on the same
    platform
  • Blind mate RF connection which mates to custom VPX
    backplane
  • Four 16-bit ADCs sampling at 160 MHz
  • Time synchronously sampling at the four ADCs
  • Remote FPGA programming support via LAN
  • Board health monitoring over I2C interface
