Analog Devices, Inc. (ADI) introduced the AD9106 quad-channel, 12-bit, and the AD9102 single-channel, 14-bit, 180 MSPS waveform generators, integrating on-chip static random access memory (SRAM) and direct digital synthesis (DDS) for complex waveform generation. ADI’s new D/A converters generate the high-speed, high-dynamic-range, multichannel complex waveforms required in applications such as ultrasound transducer excitation, medical instrumentation, portable instrumentation, signal generators and arbitrary waveform generators.

The on-chip DDS operates up to 180 MHz with a 24-bit tuning word, allowing 10.8-Hz/LSB (least significant bit) frequency resolution and providing a single frequency output for all D/A converters and independent programmable phase-shift outputs for each D/A converter. Pattern data can include directly generated SRAM-stored waveforms, DDS outputs amplitude-modulated by SRAM, or DDS frequency tuning words from SRAM providing chirp or frequency shift keying (FSK) modulation. An internal pattern-control state machine allows the user to program the pattern period for all D/A converters, the start delay within the pattern period for the signal output on each D/A converter channel, as well as the repetition rate of the pattern. A serial peripheral interface (SPI) is used to configure the digital waveform generator and load patterns into the SRAM.

AD9106/AD9102 D/A Converters Waveform Generator Features:

  • On-chip 4,096-word pattern memory
  • On-chip DDS with 24-bit tuning word
  • Sleep mode power: < 5 mW @ 3.3 V
  • Supply voltage: 1.8 V to 3.3 V
  • SFDR to Nyquist:
    • 86 dBc @ 1 MHz output
    • 85 dBc @ 10 MHz output
  • Phase noise: −140 dBc/Hz @ 1 kHz offset, 180 MSPS, 8 mA
  • Differential current outputs: 8 mA max @ 3.3 V
