Differential pairs in high-speed serial links require tight control of impedance, skew, and coupling to limit reflections, mode conversion, and crosstalk. At multi-gigabit data rates, small deviations ...

As data rates soar into the multi-gigabit range, high-speed digital (HSD) PCB design is no longer just about connecting the dots. Signal integrity (SI) and power integrity (PI) challenges can silently ...

Considerations for dividing analog and digital blocks. Decoupling techniques. Breaking down the board layers. How best to deal with grounding. Similar to building a house, it’s essential to create a ...

Designers make stackup decisions during the initial stages of PCB layout, but the consequences often emerge later in the electromagnetic interference (EMI) laboratory. Layer count, copper weight and ...
