Modeling Capacitor Impedance Vs. Frequency Using an Excel Spreadsheet
As noted in an earlier article , based on class notes from our two-day design course, getting the power subsystem design correct is the most challenging aspect of today’s high-speed PCB design process. A major aspect of this process is modeling the power supply to ensure that it will function properly in the end product. A critical part of this modeling effort focuses on being able to model capacitor impedance vs frequency. This is simple enough

Low Noise, Low EMI Power Distribution
This board has several loads on it, but it is purely a distribution board with no regulation. The main loads are the hefty 5V Tilta nano focus motor, 5V SDI to HDMI converter, 5V Tilta follows focus control, and the battery voltage powered monitor. Out of these, only the SDI to HDMI convert needs remotely clean power. The motor, however, is very electrically noisy, so it needs good isolation.

DDR3 vs. DDR4 — Lots Of Memory At Very High Speed
When it comes to memory capacity and how it’s incorporated into the present day and next-generation design, much like every other aspect of high-speed design, it’s all about accessing large amounts of data at very high speeds. The evolution of double data rate (DDR) memory has been pretty dynamic over the years. The original DDR was first introduced in 1998 followed by DDR2 in 2003, DDR3 in 2007, DDR4 in 2014, and DDR5, which has an estimated

How Material Characteristics Factor into High Speed PCB Signal Performance
Evaluating laminates for a particular PCB implementation can be a complex, multilevel process , especially when it comes to the operation of key components on the board, such as high-speed differential pairs. This article will examine some of the factors that come into play with the evaluation process: materials with a low dielectric content versus materials that are low loss; comparing the advantages and disadvantages of each of them; taking

What Happens to PCIe Signals Traversing Blind Vias at Higher Speeds?
In our one, two and three-day courses, which we conduct at technical and trade conferences as well as at private on-site classes, we will frequently be asked about particular technology trends and their impact on current designs. Of late, a number of these questions have focused on how the use of PCI Express (also known as PCIe) at higher frequencies impacts signals that change layers through vias. Limits on the number of vias in PCIe generations

Take Control of the Electronics Life Cycle with Cloud Collaboration
The electronics life cycle is a funny thing in that it relies so heavily on component lifecycles. Despite this relationship, every electronic product lifecycle follows a similar track as any other product. New products start with early adoption, later rise with sustained growth to peak adoption, and fade as new products become available with better features. Once you accept this fact, you can determine how to plan out your design and business
