Product Summary

Product Highlights

  • 1. Low noise and inter-modulation distortion (IMD) enable high quality synthesis of wideband signals from baseband to high intermediate frequencies.
  • 2. A proprietary DAC output switching technique enhances dynamic performance.
  • 3. The current outputs are easily configured for various singleended or differential circuit topologies.
  • 4. LVDS data input interface includes FIFO to ease input timing.

Parametrics

The DAC outputs are optimized to interface seamlessly with analog quadrature modulators such as the ADL5371/ADL5372/ADL5373/ADL5374/ADL5375/. A serial peripheral interface (SPI) is provided for programming of the internal device parameters. Full-scale output current can be programmed over a range of 10 mA to 30 mA. The devices operate from 1.8 V and 3.3 V supplies for a total power consumption of 3 W at the maximum sample rate. They are enclosed in 196-ball chip scale package ball grid array with the option of an attached heat spreader..
