Round and Curved PCB Design in Altium Designer
Our modern lives would not be possible without electronics. Sometimes it seems like a race to be the first person to wire everything in your house onto PCBs. With the multitude of possible device shapes and sizes, circular or rounded PCBs are becoming more popular. If you want to design your next device on a round PCB, your design software needs CAD and layout tools that don’t constrain you to working on rectangular PCBs. When you work with

Differential Pair Length Matching: Best Practices for Signal Integrity
Take two signals and send them down a parallel bus or differential pair. How can you be sure the downstream receiver will latch to your signals? If your signals don’t arrive at the same place and at the same time, then gates in your receiver won’t latch at just the right moment. This delicate balance can be like walking a tightrope across a cliff, and it can be difficult to maintain differential pair length matching by eyeing your trace lengths

How to Perform Differential Pair Tuning in Altium Designer
In order to properly suppress common-mode noise, differential pairs should be routed in parallel with symmetry and matched lengths. Today's CAD tools make it easy to come close to all three objectives, but only if you have the right design tools. Instead of eyeing out your different pair lengths, the interactive routing tools in Altium Designer make differential pair length matching easy. You can encode permissible length mismatches as design

How to Create a Test Point Schematic Symbol and Footprint in Altium Designer
Bare board testing is like a moment of truth, where your fabricator and your design team determines whether a board passes inspection. Some basic test fixtures and testing points should be indicated in your schematic and your PCB layout, especially when they are critical for evaluating board functionality. So what is the best way to do this? You might rely on your manufacturer to assign test points, but for critical circuit blocks, you should

Decoupling Capacitor and Bypass Placement Guidelines
Power integrity problems are normally viewed from the perspective of the power supply, but looking at the output from ICs is just as important. Decoupling and bypass capacitors are intended to compensate for power fluctuations seen on the PDN, which ensures your signal levels are consistent and a constant voltage is seen at the power/ground pins on an IC. We’ve compiled some important bypass and decoupling capacitor design guidelines to help you

USB Charger Project in Altium Designer: Part 2
In a previous blog post, I showed the process for building a schematic for a custom USB charger board using Altium Designer. This board requires a small number of components and some particular attention to the USB power supply design/decoupling networks, but aside from this it’s quite easy to build out the connections you need for the USB A connectors. Here, I’ll show the strategy for translating this schematic into a compact board with a small

USB Charger Project in Altium Designer: Part 1
When I’m in my office, I keep my pluggable USB charger around, otherwise the battery on my phone is likely to run out. If you want to build your own USB charger, you can create your own USB charger board with the powerful schematic design and layout tools in Altium Designer. Here, I’ll present the overall design process for a portable USB charger. The charger requires 12 V of power and charges two external devices through two USB ports. We’ll

PCB Design for Radio-Over-Fiber Technology
It’s possible that radio-over-fiber technology is one of the least discussed aspects of fiber telecom networks. However, it stands to be one of the many portions of telecom infrastructure for bringing broadband wireless access to remote areas. This approach is likely to play a major role for future 5G infrastructure in rural areas where a standard wireless backhaul is not possible or cost-prohibitive. Just like any other electronic system, radio

Transmission Line Impedance Calculation With Altium Designer
Today’s PCBs contain many transmission lines. Combine this with increased clock frequencies and data rates and the result is a critical challenge to high-speed design. Neglecting these dynamics can undermine product development by compromising performance, power consumption, EMC/EMI compliance, and more - leading to delayed design cycles and opening gaps that can be exploited by your competition. Hone your high-speed design skills by joining us as we discuss the typical transmission lines encountered in today’s designs, the PCB variables that affect impedance, as well as how to create, calculate, and design transmission lines in Altium Designer. Learn how to maximize the built in SIMBEOR® engine by Simberian to craft impedance profiles and manage transmission lines in your designs. This Live Webinar recording covers the following: Current trends in electronics development PCB transmission line model and impedance calculations Transmission line with specified impedance in Altium Designer Don’t pass up on this opportunity to experience the industry’s best in class design experience!
