1. A method for distributing a source clock signal comprising:

  • transmitting the source clock signal from a third position to a first position spaced apart from the third position with a first transmission line having a first delay;

    generating a first clock signal responsive to the source clock signal at the first position;

    transmitting the first clock signal to a second position spaced apart from the first position;

    generating a second clock signal responsive to the first clock signal at the second position;

    feeding back the second clock signal to the first position with a second transmission line having a second delay; and

    locking the second clock signal with the source clock signal, thereby controlling the skew between the second clock signal and the source clock signal;

    wherein the first position is located intermediate the third position and the second position; and

    wherein the delay characteristics of the first delay is similar to the second delay.
