NORWOOD, Mass., Oct 08, 2012 (BUSINESS WIRE) —
      Devices, Inc. (ADI), the leading provider of data-conversion
      technology* and longtime collaborator with the medical imaging industry,
      today introduced the industry’s first octal ultrasound receiver to
      feature an on-chip JESD204B serial interface. By incorporating the
      5-Gbps JESD204B interface, ADI’s new AD9671 octal receiver reduces
      ultrasound system I/O data routing by as much as 80 percent compared to
      other data interface standards. The resulting savings addresses the
      needs of manufacturers designing small, high-performance ultrasound
      systems by simplifying ultrasound equipment board design while better
      meeting industry demand for higher data rates, larger channel counts and
      greater image resolution.

      The AD9671 receiver conditions eight channels of data from RF to a
      baseband frequency, reducing the processing load on the system FPGA
      (field-programmable gate array) by at least 50 percent compared to other
      receivers. The AD9671 integrates a low-noise amplifier, variable gain
      amplifier, anti-aliasing filter, and a 14-bit A/D converter with the
      industry’s highest sample rate (125 MSPS) and SNR (signal-to-noise
      ratio) performance (75 dB) for enhanced ultrasound image quality. The
      new octal receiver is the latest addition to Analog Devices’ award
      winning ultrasound receiver portfolio and is designed for mid- to
      high-end portable and cart-based ultrasound systems.

      “By introducing the first octal ultrasound receiver with a
      multi-gigabit, serial data link, we are enabling ultrasound equipment
      designers to shrink the number of interconnects between their data
      converters and FPGAs,” said Pat O’Doherty, vice president, Healthcare
      segment, Analog Devices. “By incorporating the JESD204B serial
      interface, the AD9671 receiver not only simplifies PCB design and debug,
      it allows manufacturers to continue lowering design costs and reducing
      system size while maintaining excellent overall system performance.”

      AD9671 Octal Ultrasound Receiver with Digital I/Q Demodulation

      As with ADI’s recently released AD9670 octal ultrasound receiver, the
      AD9671 integrates a digital I/Q demodulator, programmable-oscillator and
      16-tap FIR (finite-impulse response) decimation filter to reduce FPGA
      data bandwidth requirements, while additionally combining multiple
      channels into a single CML (current-mode logic) data lane. The AD9671
      provides a continuous wave (CW) processing path with an analog I/Q
      demodulator that has harmonic rejection to the 13th order, which allows
      designers to reduce the number of filter components to lower system
      cost, reduce design complexity and improve signal sensitivity. The
      CW-mode output dynamic range is more than 160 dBc/ a^sHz per channel.
