Abstract
A phase detector device and a clock regeneration device for phase centering when incoming data are sampled at a clock rate, which is in particular substantially half the size of the high clock rate of the incoming data, are provided. The device includes a plurality of flip-flops. The phase detector and the clock regeneration device further include correction devices for producing a correction signal. The correction signal can be passed to an integrator in which a control signal for an oscillator can be produced from the correction signal and the output signals of the first, second and third weighting devices. The clock rates of the first and the second clock signals correspond to substantially half the high clock rate. The phase of the first clock signals is shifted by 180° with respect to the phase of the second clock signals.
