VDJ Ultra High-Speed Variable Delay Lines

The VDJ type (VDJ1010) of dual in-line variable delay lines is available in one standard device or to your custom specifications.


Features

  • High-speed variable delay line that allows broad usage with such ultra-high-speed logic elements as the ECLinPS.
  • Also suitable for use in a broad range of applications in analog circuits. The part is in a miniaturized, hermetically sealed package that can be easily washed.
