Circuit topology for high-speed printed circuit board

A layout method within a printed circuit board (PCB) comprising the steps of:

• setting a driving circuit and a plurality of receiving circuits on the PCB;
• coupling the driving circuit to a node via a transmission line;
• and
• coupling each of the receiving circuits to the node separately via a transmission line.

A method for layout arrangement of a printed circuit board (PCB), comprising the steps of:

• defining a first circuit on a PCB;
• defining at least two second circuits on said PCB capable of performing signal interchange with said first circuit respectively and independently;
• and
• coupling said first circuit to each of said at least two second circuits by means of a commonly-used electrical transmission line firstly and a respective branch electrical transmission line extending from an end of said commonly-used transmission line away from said first circuit secondly, said branch transmission line having a length of the shortest distance between said end of said commonly-used transmission line and said each of said at least two second circuits.
