Abstract

A method for determining whether to trigger a reset of a delay locked loop ("DLL") comprising calculating the difference in time between a reference clock and a delay clock; comparing the difference in time to the amount of time required for a reset signal to reset said DLL; and generating the reset signal to reset the DLL if the reset time is less than the difference in time between the reference clock and the delayed clock.
