Product Brief
Press Release
Bitshark™ FMC-1RX card

The Bitshark™ FMC-1RX is a broadband, high performance single-tuner RF receiver card that is compliant with the FPGA Mezzanine Card (FMC/VITA 57) digital interface standard. It supports a tuning range between 300 MHz and 4 GHz, while supporting user-defined channel bandwidths up to 50 MHz. Digitized baseband I/Q samples are provided by dual A/D converters, and are accessible on the FMC interface for use by the host system.

The Bitshark™ FMC-1RX is targeted at commercial wireless radio applications including software defined radio (SDR) and cognitive radio (CR). A wide range of frequency bands are supported:
• GSM (850/900/1800/1900 MHz)
• iDEN (800 MHz)
• CDMA2K/EVDO (450/800/1900/2100 MHz)
• UMTS (Bands I-XIV)
• TD-SCDMA (1.9/2.0/2.4 GHz)
• WiFi/802.11b/g (2.4 GHz)
• WiMAX/802.16 d/e (2.3-2.7 GHz, 3.3-3.8 GHz)
• LTE (Bands 1-40)
• TV Whitespace (400-700 MHz)
• ...plus many others

Reference Design

Reference Design

To enable evaluation and integration of the Bitshark™ FMC-1RX card with the VITA-57/FMC digital interface, an example spectrum analyzer application is delivered with the FMC-1RX. This consists of an FPGA reference bitstream (targeting the Xilinx SP605/ML605 FPGA boards) and a cross-platform PC-based spectrum analyzer application for displaying data received from the FMC-1RX card.

Evaluation Setup

A typical setup for evaluating the FMC-1RX card with the provided spectrum analyzer software is shown above. Note that the FPGA Host Board is not provided.

FPGA Reference Design

Features of the FPGA Reference Design:

  • A/D high-speed data interface (LVDS synchronization / deserialization)
  • SPI-based interface for A/D control (writing to A/D internal registers)
  • DC offset correction block
  • I/Q imbalance correction block
  • UART-based control / data interface for communication with PC
  • Targeted at both Xilinx SP605 and ML605 evaluation boards

The Bitshark™ FMC-1RX Development Kit (Bitshark™ FMC-1RX-DVK) comes with the Verilog source code (with unlimited use license) for the FPGA reference design described above.

Spectrum Analyzer

Features of the PC-based spectrum analyzer:

  • Control of FMC-1RX configuration (RF center freq, RF gain, baseband gain, baseband filter bandwidth, A/D sample rate)
  • Display of time domain plot
  • Display of frequency domain plot
  • Display of I vs Q plot
  • Compatible with multiple host operating systems

The Bitshark™ FMC-1RX Development Kit (Bitshark™ FMC-1RX-DVK) comes with the Java source code (with unlimited use license) for the Spectrum Analyzer application described above.
