  • Patent number: 5319369
    Abstract: Typically, a parallel-to-serial converter comprises a parallel-to-parallel register and a parallel-to-serial register. According to the prior art, a first clock signal the transfer of incoming parallel data words to outputs of the parallel-to-parallel register whereas the loading of the parallel-to-parallel register is rhythmed by a second clock signal which is independent of the first clock signal. According to the invention, a local base time produces the second loading clock signal and two clock signals substantially in phase-opposition so that there is time dependence between these signals. A phase analyzing circuit derives a control signal for selecting one of the two clock signals which are in phase-opposition as a function of a phase shift between the incoming parallel data words and the first clock signal.
