Do you want to use USB3, Gbit Ethernet, PCI-Express or DVI/HDMI in your custom PCB designs? This talk may be for you. Intermediate understanding of electrical engineering concepts (impedance, wave forms, digital signals) is recommended. I will use KiCAD to demonstrate concepts.\n\nThanks to the ubiquitous availability of fast electronic components, custom PCB design incorporating high-speed data transmission has become incredibly affordable. Two particular technologies are very useful for transmitting fast digital signals on a PCB: [Differential signalling](https://en.wikipedia.org/wiki/Differential_signalling) combined with [microstrip traces](https://en.wikipedia.org/wiki/Microstrip) into differential pairs. This talk presents practical aspects of designing PCBs with differential pairs, as well as why they are so useful.","original_language":"deu","persons":["seto"],"view_count":36,"promoted":false,"date":"2026-06-13T17:00:00.000+02:00","release_date":"2026-07-05T00:00:00.000+02:00","updated_at":"2026-07-06T16:15:07.211+02:00","tags":["110718","2026","cosin2026","Hardware","Lecture
