ABSTRACT:
A time interval division circuit that generates a delayed signal that is a precise integer fraction of the clock cycle. A digital delay loop including a digital delay line is locked to the clock cycle and controls a second digital delay line. The delay line characteristics determine the fraction of the clock cycle generated. The time interval division circuit tracks the clock cycle, rather than on-chip circuit delays as conventional delay lines.
