Abstract
An embodiment of the present invention implements a linear feedback shift register (LFSR) as a counting device for an integrator of a DFE circuit. In embodiments of the present invention, the particular count sequence need not be known, instead only boundary values need be known. For example, for a LFSR having a predetermined count sequence, a digital integrator controller need not know every value of the count sequence. Instead, the digital integrator controller detects predetermined boundary values such as a minimum or maximum count.
