摘要：A delay locked loop includes initialization circuitry that ensures that a DLL isinitialized to an operating point that is not to close to either end of a delay vs. controlvoltage characteristic. The initialization circuitry forces the DLL to initially search for a
lock point starting from an initial delay, the delay is varied in one direction, forcing theDLL to skip the first lock point. The initialization circuitry only allows the DLL to vary thedelay of the voltage controlled delay loop in the one direction from the initial delay untilthe operating point is reached.
