Abstract
The present invention relates to a circuit board having a plurality of integrated circuits provided thereon, wherein each integrated circuit (IC) receives a common clocked input reference signal and outputs a dam signal. Each integrated circuit is provided with a de-skewing circuit which compensates for signal delays in the IC so as to synchronize the output data signal with the clocked input reference signal. The de-skewing circuit is operative to generate a simulated signal delay to the input signal which emulates the signal delays of the IC.
