摘要： A synchronous output signal generated by an integrated circuit (IC) component is synchronized to an applied clock signal for each individual IC component. A variable feedback delay in the IC component is incrementally altered to alter the phase skew between the clock signal and the output signal. The relative phase order of the clock and output signals is monitored in the IC component. In response to detecting a swap in the relative phase order of the clock and output signals, the variable feedback delay ceases to be altered. In some embodiments, the IC component may be a SDRAM component.

摘要： An improved delay chain for use in a delay locked loop which provides smooth phase adjustment and high resolution. In a delay chain having a series of cascaded unit delay elements, the outputs of a pair of contiguous delay elements (N, N+1) are selected for input to a phase blender. A coarse delay adjustment is carried out by selecting the outputs of the next pair of contiguous delay elements (N+1, N+2) and thus affects only one of the phase blender inputs. The phase blender provides a fine delay adjustment by generating an output whose phase is a weighted combination of the inputs, the weights having an inverse relationship. A coarse delay adjustment which affects an input of the phase blender is carried out when the weighting of that input is zero. Fine-to-coarse hand-over problems which characterize known delay locked loops are thus avoided.
