ABSTRACT:
A transition detector for providing a pulse signal upon detection of a transition occurring in an input data signal, a variable delay line for generating a first delayed data signal which lags the input data signal by a variable delay amount, a fixed delay line for generating a second further delayed data signal which lags the first delayed data signal by a fixed delay amount, and a phase comparator for comparing a transition of the second delayed data signal with a clock signal phase are disposed. The phase comparator controls the delay amount of the variable delay line such that the transition of the second delayed data signal is substantially phase matched with a rise edge of the clock signal. The first delayed data signal is output together with the clock signal.
