Abstract (en)

[origin: WO9849802A1] According to the invention, a delay signal from the detected phase status is detected in a phase adjustment circuit used to generate a systemic clock signal in relation to an incoming data signal from a locally existing clock signal, wherein a memory which is addressed by the detected phase status produces an allocated delay signal. In a special embodiment, the memory is allocated an address whose last detected delay is compensated. In another embodiment, a control with a memory is common to circuits for several data signals. The phase adjustment, which automatically recognizes a loop that is better suited for timing than the loop that is momentarily used, can be fully integrated and avoids areas of the circuit which are operated with a higher bit rate than that of the clock signal.
