Coupling capacitors find plenty of uses in analog applications and on differential protocols, acting essentially as high pass filters that remove DC bias carried seen on a signal. In the case of PCIe, there are a few reasons to place AC coupling capacitors on differential pairs beyond the fact that AC coupling capacitors are listed in the standard. In this article, we’ll look briefly at where to place coupling capacitors on PCIe links, as well as the reasons these are placed on PCIe links.
We are happy to announce that the Altium Designer 22.7 update is now available. Altium Designer 22.7 continues to focus on improving the user experience, as well as performance and stability of the software, based on feedback from our users. Check out the key new features in the What's New section on the left side of this window!
Design to cost is a lofty idea that is only perfectly executed when supply and demand for components are in perfect harmony. Unfortunately, the current landscape for component sourcing makes design to cost more of a balancing act rather than an exercise in price reduction. To help designers in their efforts to balance cost, capabilities, and procurement, we created this ebook to help users understand how modern supply chain tools can help in these complex design problems.
One major benefit of using a version control system is the ability to compare PCB design revisions against one another. If you are comparing PCB designs, you need a version control system that is electrically intelligent. It’s important to know who made a change, and when they made it. Altium Designer® and Altium 365® make file comparison easy.
Stubs are an important topic in high-speed PCB design, and there is a longstanding guideline that stubs should always be removed from all vias on high-speed digital interconnects. While stubs are bad for high-speed lines, they do not always need to be removed. What is more important is to predict the loss profile and frequencies, and to floorplan appropriately to try and prevent such losses.
Once you finish your placement and routing in your PCB layout, it can be tempting to wrap up the layout and send everything in directly to manufacturing. The reality is that the board may still need some work before it is considered finished. The cleanup you perform at the final stage of PCB layout will help you catch any outstanding errors that can't be programmed into your DRC engine, and it gives you a chance to add any outstanding details to the surface layers.
In this project we’ll be building a moderate sized LED panel on insulated metal substrate (IMS). This light panel has three different white balance High CRI LED types on it, warm, neutral and cool. By changing the brightness of the different white balances, the light from the panel can be adjusted to match other lighting, making it perfect for film use - but also creating perfect lighting for electronics work. As with all my projects, this LED panel is open source, you can find the Altium project files over on my GitHub released under the permissive MIT License.
Every design should begin with selecting the materials that will appear in the PCB stackup, as well as arranging layers in the stackup to support layout and routing. This section of our PCB manufacturing andc DFM crash course focuses on selecting the right materials for your PCB design. Materials should be selected given the particular design requirements outlined in your specifications.
FPGAs come in quad or BGA packages that can be difficult to floorplan, especially with the high number of I/Os often implemented in these components. FPGAs offer a lot of advantages in terms of their reconfigurability, but they can require a lot of effort to layout and route without headaches. If you’ve never worked with an FPGA in your PCB layout, we have some guidelines that can help you get started.
S-parameters are fundamental quantities in signal integrity, and an ability to understand them from measurement or analysis is very important. If you have a 3-port network, like a power divider or circulator, it may appear that you must use a 3-port VNA to measure these S-parameters. It is always acceptable to measure between two ports, but you need to know what exactly it is you are measuring. In this article, we’ll look at the relationship between the true 3-port S-parameters with a 2-port measurement.
