skew sources high speed PCB

Addressing Skew Sources in High Speed PCBs Sometimes, when we talk about skew, we aren't as specific as we should be. Most discussions of skew and jitter deal with the type of skew incurred during routing, namely due to length mismatches in differential pairs and fiber weave-induced skew. In fact, there are many different sources of skew that contribute to total jitter on an interconnect, and it's important to quantify these in serial and parallel buses that require precise timing control Read Article

Ebook: Guide to Using Ferrite Beads in a PCB Ferrite beads in a PCB are the stuff of myth, but there are legitimate uses for ferrite beads and other ferrite components. In this e-book, we’ll examine some uses of ferrite beads in a PCB, as well as other magnetics. Download PDF

PCB copper roughness

How Much Copper Roughness in Your PCB is Too Much? When we talk about copper roughness, we always bring it up as if it were a universally bad thing. The fact is, some circuits will always function just fine even if the copper is rough. As long as your traces are fabricated to spec in every other area, the roughness of the traces might not matter as long as your operating frequency or bandwidth are low enough. Just what constitutes “low enough” and when is the effect of roughness so small that we Read Article

Parasitic Extraction with an Electromagnetic Solver in PCB Routing

Parasitic Extraction with an Electromagnetic Solver in PCB Routing Parasitic extraction: the integrated circuit design community must grapple with this task on a daily basis, especially once gate features are reduced below ~350 nm and chips run at high switching speeds. The PCB community also has to deal with this idea in order to better design power delivery networks, interconnects with precise impedance, and properly quantify crosstalk and coupling mechanisms. There are many 3rd party applications that can be Read Article

Mode conversion

A Guide to Mode Conversion, Its Causes, and Solutions Differential pairs are most often discussed in terms of their impedance and length matching tolerance, both with the goal of ensuring proper termination at the receiver and suppression of common mode noise. On interconnects, such as board-to-board connections or cascaded transmission line arrangements, you have an important EMC compliance metric that is sometimes overlooked. This is mode conversion, which can be visualized in an S-parameter Read Article
