Abstract
Systems and methods associated with control of clock signals are disclosed. In one exemplary implementation, there is provided a delay-lock-loop (DLL) and/or a delay/phase detection circuit. Moreover, such circuit may comprise digital phase detection circuitry, digital delay control circuitry, analog phase detection circuitry, and analog delay control circuitry. Implementations may include configurations that prevent transition back to the unlocked state due to jitter or noise.
