Abstract:
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; andlocking 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; andwherein the delay characteristics of the first delay is similar to the second delay.
