PCB Design in Altium Designer with Differential Data Transfer
Differential data transmission lines usage can be challenging for even experienced designers. First you need to be familiar with the concepts of differential data transmission, find out why it is used, and what the potential advantage for your signal. This webinar will help you determine what part of your designs need differential pairs implementations and how to create such pairs with a given wave impedance in Altium Designer.

Why Most Via Impedance Calculators Are Inaccurate
The problem with every via impedance calculator that I have seen is simple: they are incomplete or totally wrong. The “incomplete” part refers to a lack of context; these calculators can roughly reproduce a well-known estimate from a legend like Howard Johnson in his Digital Design textbooks. However, these calculators never provide insight into what they are actually calculating, or where the calculated via impedance is accurate. Keep reading to see why these calculators get it so wrong, as well as the context surrounding via impedance.

Buck Converter Simulation in Altium Designer
When designing high power circuits (usually very high voltage and/or current), you’ll need to create a regulator from scratch and place it in your PCB layout. It's also the case that you may want to model a real component using discretes in a simulation in order to qualify the system's expected operating regime. As part of buck converter design, you can easily run a buck converter simulation directly in Altium Designer’s schematic editor. Here’s how you can access these features in the newest version of Altium Designer.

Overview of the PCIe 6.0 Standard
Just as you get used to PCIe 5.0, they decide to release another standard! The newest iteration of PCIe is Gen6, or PCIe 6.0. PCIe 6.0 brings a doubling of channel bandwidth through introduction of PAM-4 as the signaling method in high-speed differential channels. This signaling method is a first for PCIe, and it’s an important enabler of the doubled data rate we see in the current standard. In this article, I’ll run over the important points in the standard and what PCB designers can expect when designing these channels.

SPI vs. I2C: How to Choose the Best Protocol for Your Memory Chips
One of the common implementations of SPI and I2C in a PCB layout is as a protocol for reading and writing to an external Flash memory. Flash chips are a very common component in embedded systems and can offer high capacities of non-volatile memory up to Gb values. When choosing a memory chip, you'll want to match the application requirements and functionality with the bus speed you need for read and write operations in your memory chip. There is also the matter of the type of Flash memory you'll need to access (NOR vs. NAND).

Tips & Tricks: Board Shape Creation
Being able to design a board in your ECAD environment doesn’t mean that it is manufacturable in real life. You have to make sure your CAD representation won’t have any problems in the real world by taking some precautions. For example, there are certain areas that need to be free of components and have specified clearances like your board edge. This webinar will help you get acquainted with the creation and modification of your board shape so that you can ensure manufacturability.

Is There an SPI Trace Impedance Requirement?
There is no SPI trace impedance requirement? The reality is that SPI lines only start to need impedance control when the length of the interconnect becomes very long. And because there is no specific impedance requirement in the bus, you have some freedom in channel design and termination. So what exactly qualifies as “very long” and when is some termination method needed? We’ll break it down in this article.
