Abstract: A coarse lock detector for a delayed locked loop (DLL) is disclosed. The coarse lock detector includes multiple detection cells. Each detection cell receives a delayed clock phase and an output of a previous detection cell as inputs. To increase time for the output of the previous detection cell to propagate, the detection cells are arranged in groups such that the output from the previous detection cell is generated by a detection cell which is more than one detection cell previous.
