Should You Use Tight vs. Loose Differential Pair Spacing and Coupling? We get a lot of questions about trace impedance and how to calculate the right trace size to hit a specific impedance in a manufacturable PCB. Just as important as determining an appropriate trace width for a single-ended trace is determination of an appropriate spacing between two traces in a differential pair. So the question is, how close do the traces in a differential pair need to be to each other, and is the need for “tight coupling” really Read Article Six Weeks with Zach Peterson Guest Host Expert PCB Designer and Altium Academy instructor Zach Peterson to takeover OnTrack Podcast for the next six weeks.

Read Article Getting Started With High Current PCB Design High current PCB design brings its own set of challenges, both in terms of PCB layout and safety. Here’s what you need to know. Read Article Common Mode Choke Selection Noise on power supply lines can be a major headache. We'll examine how to select a common-mode choke to help eliminate common-mode noise. Read Article Can You Design a Rotation-Proof Connector Pinout? There are times where your connector pinout needs to be adaptable and reversible. What’s the easiest way to do this? Use a rotation-proof connector in your PCB. Read Article Power Delivery Systems Design This article is intended to define the new challenges and provide guidance in how to successfully engineer the Power Delivery System (PDS) so it meets the needs of new technologies. As integrated circuit technology allows for billions of transistors on a single IC, it has resulted in very powerful systems on a chip. This has made it possible to put the equivalent of supercomputers inside video games, cell phones, and a host of other products that Read Article Controlled ESR Capacitors: Should You Use Them for Power Integrity? I can’t think of a single product I’ve built that doesn’t require capacitors. We often talk a lot about effective series inductance (ESL) in capacitors and its effects on power integrity. What about effective series resistance (ESR)? Is there a technique you can use to determine the appropriate level of resistance, and can you use ESR to your advantage? Like many answers to important engineering questions, the answer is “it depends.” One type of Read Article Routing Requirements for a USB Interface on a 2-Layer PCB In an earlier blog, I discussed some of the basic points in preparing routing rules for 2-layer PCBs to support routing and layout with digital signals. In particular, we looked at some of the basic stackup and routing rules needed to support a digital interface like I2C or SPI on a 2-layer PCB. When working with these interfaces, a few simple guidelines can help ensure signal integrity in your board and cut down on EMI. What about an impedance Read Article Ferrite Core Selection and Design Decisions When designing a transformer or using a ferrite core inductor, you must use the correct design process, and there is no substitution for real-world final testing. Let’s look at the process. Read Article Pagination First page « First Previous page ‹‹ Page46 Current page47 Page48 Page49 Page50 Page51 Next page ›› Last page Last » Load More
