Controlled impedance is not science fiction… Especially when you know how to calculate your controlled impedance traces. But, do you? Open our free Impedance Calculator – which will help you answer some of the following questions – and get ready to take the quiz!
During DesignCon 2018, Sierra interviewed the Signal Integrity Evangelist Eric Bogatin. We could not resist to ask him about his first DesignCon. “You know, I looked back at all the DesignCons that I’ve been to, and I think it was in 1992, he said. It was back in the old days when it was the HP High-Speed Digital Symposium, so it’s been a long time.” Listen to this PCB expert’s thoughts on technology, crosstalk, PAM-4, educating the new class of PCB designers, and the signal integrity market.
After establishing what a PCB transmission line is and talking about signal speed and propagation delay, last week, we discussed the critical length, the controlled impedance, and the rise/fall time of a PCB transmission line. Today, we are going to explain how to analyze a PCB transmission line using quantities, such as voltages and currents, and line parameters, such as resistance, inductance, capacitance, and conductance.
After explaining the importance of the signal speed and propagation delay in a PCB transmission line, we are now going to talk about the transmission line effects, the critical length, the rise/fall time and when the length of an interconnection is to be considered as a controlled impedance transmission line.
During DesignCon 2018, we met Bill Hargin, “Director of Everything” at Z-Zero, an innovative PCB stack-up design company. Bill told us about Z-Zero’s stack-up tool and shared some precious tips for PCB designers.
On Wednesday, February 22, the Sierra team flew to San Diego to attend a two-day workshop on noise, electromagnetic interference and signal integrity control in high-speed PCBs. This event – called PCB2DAY – was initiated by UP Media, the publisher of PCD&F Magazine and the host of PCB West.
