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)
