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

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

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

Utilizing a PCB Transmission Line Calculator Makes Design Easier
PCB transmission line calculators are a dime a dozen, giving you the tools you need to calculate lossless impedance, lossless propagation delay, or simple things like DC resistance. These quantities are nice to know, but they don't tell you the whole story about your design. Online calculators are also known to give incorrect results when used for impedance calculations, especially because they cannot consider fundamental phenomena like

EMI Shielding Techniques You Can Use in Your PCB Design Software
Electromagnetic interference (EMI) is such a problem that governments around the world have placed limits on the amount of EMI an electronic device is allowed to generate or receive. Your electronic device needs to be designed to prevent unintentional radiation and suppress conducted noise up to a very high-frequency value. This is not a simple matter of adding filtering on every circuit in your PCB layout, it’s about considering the entire
