GaAs logic for multi-Gb data generators

Abstract

Three GaAs MSICs, consisting of a 1023b PRBS generator, recurrence-relationship test circuit and a multiple-8b word generator will be described. The PRBS circuits generate and detect a maximum-length sequence at 2.5Gb rates. The word generator forms groups of 8b words, whose content and number can be dynamically controlled at 5Gb.
