Abstract
A system for compensating for variations in the frequency of an input clock signal having a first frequency includes a coarse counter that receives the input clock signal, counts a predetermined number of clock pulses of the input clock signal, and generates a coarse compensated clock signal having a second frequency. A first compensation module adjusts a clock pulse of the input clock signal based on a coarse compensation value. A residual period adjustment module accumulates a fine compensation value for each clock pulse of the coarse compensated clock signal. A fine counter operates at a third frequency of a fine clock signal, receives an adjusted delay value based on the accumulated fine compensation value, counts a number of fine clock pulses in each clock pulse of the coarse compensated clock signal, and generates a fine compensated clock signal having the second frequency.
