Abstract:
An apparatus for locking out a source synchronous strobe receiver, including a delay-locked loop (DLL) and one or more receivers. The DLL receives a reference clock, and generates a select vector and an encoded select vector that both indicate a lockout time. The select vector is employed to select a delayed version of the reference clock that lags the reference clock by the lockout time. The lockout time is slightly less than a number of cycles of the reference clock. The one or more receivers are each coupled to the delay-locked loop. Each of the one or more receivers receives the encoded select vector and a corresponding strobe, and locks out reception of the corresponding strobe for the lockout time following transition of the corresponding strobe. The encoded select vector is employed to determine the lockout time by selecting a delayed version of the corresponding strobe.
