Logic Level Translators/Level Shifters/Logic Convertors

Mini Modular Instruments > Logic Level Translators/Level Shifters

Applications:

  • Self-contained, high-speed modules enable interconnections among different logic families
  • Comparator modules convert very small signals or sinewaves to logic levels
  • Oscilloscope modules allow connection of NECL/PECL/LVPECL circuits to ground-referenced instruments

Features:

  • Differential or single-ended inputs
  • Differential outputs (except PRL-470A)
  • 2 channels per module (550 series has 4 ch./module) for synchronous CLK/DATA translation
  • Output fmax up to 3 GHz
  • All modules are also line drivers, and can drive long cables
  • Includes AC power adapter

* These products require a differential input signal. All other products accept single-ended or differential inputs, except where the input logic family is differential by definition (e.g. RS-422, 124 Ω NECL, and LVDS)
Product numbers without links do not have updated webpages. Please contact factory for details. Table entries "S.O." indicate products that are Special Order only. Special Orders require a non-recurring engineering fee (NRE) or a minimum quantity order. Please contact factory for details.
