The DLL circuit detects a frequency of an external clock signal and adjusts a coarse delay during a DLL circuit operation, thereby quickly terminating a feedback operation of the DLL circuit and having a reduced circuit area of a delay line. The method begins by placing a sash on a glazing table, wherein the sash defines an opening therein and has a glazing leg extending into the opening in the sash. The first and second contacts are received in the insulative housing with mating portions thereof received in the first and second mating segments, and leg portions bending downwardly to be located in the two parts of the rear wall.
