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!

Reflecting on Your Design, Part 2, What Do Reflections Do to a Signal?
In part 1 of this article, I described what transmission line reflections are, how they are created and what the resulting waveforms look like. This part of the article will discuss what reflections do to a signal. Figure 1 is a typical 5V CMOS driver driving a 50-ohm transmission line that is 12 inches or approximately 2 nanoseconds long. There is a CMOS receiver at the end of the line that is a tiny parasitic capacitor. For these purposes, it

Power Plane and Ground Planes: Should You Use Your PCB Power Plane as a Return Path?
Power planes (sometimes called a power layer) and ground planes are important for more than just distribution of supplying power. When defining reference planes, both with impedance controlled routing and in managing return paths, your stackup might force return currents to pass into a PCB power plane before being coupled back to a ground layer. Even though you define a GND reference layer as a the basis for your impedance-controlled trace width

Pros and Cons of Orthogonal Trace Routing in Multilayer PCBs
What would limit your use of orthogonal trace routing? Like most design questions, it depends on your signal speed and stackup, as well as placement in the PCB layout. Read this latest PCB design blog by expert Zachariah Peterson to learn more.

Reflecting on Your Design—What are Reflections and What Do They Do to a Signal? Part One
In describing what happens when an electromagnetic field or wave is traveling on a transmission line, we often talk about the various things that can disrupt that wave. Among the most common of these things are reflections. Part 1 of this article will describe what reflections are and how they are caused. The second part will discuss what they do to a signal. Then, a separate article will address how reflections are controlled by terminations

The Fundamentals of High Speed SerDes Design
High speed SerDes design goes far beyond computer peripherals The challenges in high speed SerDes design filter right down to the PCB level and are all about backplane/daughtercard design, transmission line layout, selecting proper equalization schemes, and much more. This even gets down to the fundamentals, where stackup and power integrity become critical when driving transmitters and receiver ICs. If you’re designing a PCB as part of a SerDes

DDR5 PCB Layout and Signal Integrity Guidelines: What Designers Need to Know
Release of the DDR5 standard was announced in July 2020, about 18 months after the announced development of the first RAM module following the proposed standard. The standard allows peak speeds in excess of 5200 MT/sec/pin (compare that to 3200 MT/sec/pin with DDR4), with JEDEC-rated speeds up to 6400 MT/sec/pin and channel bandwidth increased up to 300 GB/s. Demand for this new generation of memories with 8, 16, and 32 GB capacities should

MIPI Physical Layer Routing and Signal Integrity
MIPI physical layer routing (C-PHY) is typically used to connect these smartphone cameras to a processor. When most designers talk about routing standards, particularly for advanced devices, they typically refer to differential routing standards (e.g., LVDS) that enable high data rates. These signaling standards have proliferated computers, networking equipment, smart electronics, and other areas, and they have been critical for operating with
