PCB Layout – Impedance Control

Modern electronic circuits often use high speed communication channels to enable information transfer and elaboration. Cell phones and PC mother boards could be typical system examples we use on a daily basis. Electrical signals, that must travel to the PCB to let a LED blink, do not typically drive any major concerns, but if the signal is going to use a protocol working at 1Gbits/s, the PCB traces need different considerations. The article will describe “why” and “how” to make sure the PCB can enable signal integrity along the trace, and make sure that the information is transferred correctly. Special focus will be also given to the manufacturability of the PCB.
