    Abstract: A method for propagating a signal from an output driver on a PCB to a number of chips on the PCB. The signal is propagated from a first transmission line connected to the output driver, to a second transmission line connected to the first transmission line and a first chip, and to a third transmission line connected to the first transmission line and a second chip. The second transmission line has a length greater than or equal to 10 times the length of the first transmission line, and the third transmission line has a length greater than or equal to 10 times the length of the first transmission line. The lengths of the first transmission line, the second transmission line, and the third transmission line cause a reduction in reflections of the signal due to a change in impedance at a junction of the first, second, and third transmission lines.
