  • Systems and method for a delay locked loop with false-lock detection
    Patent number: 7301379
    Abstract: A DLL comprises detection circuitry configured to detect a too_slow and a too_fast operating state and correction circuitry configured to correct operation of the DLL when a too_fast or too_slow state is detected. The correction circuitry can be configured to swallow a pulse of the input clock signal when a too_fast condition is detected. The correction circuitry can also be configured to force the DLL into a too_fast operation state, when a too_slow operation state is detected. The correction circuitry can then also be configured to swallow a pulse of the input clock signal once the DLL is in the too_fast operation state.
