Transmission Line Impedance: The Six Important Values Transmission Line Impedance: The Six Important Values When looking through the various transmission line impedance values, characteristic impedance and differential impedance generally stand out as the two important values as these are typically specified in signaling standards. However, there are really six transmission line impedance values that are important in PCB design. Sometimes there are seven, depending on which textbooks or technical articles you read. Characteristic impedance equations Read Article
PCBs vs. Multichip Modules, Chiplets, and Silicon Interconnect Fabric PCBs vs. Multichip Modules, Chiplets, and Silicon Interconnect Fabric (2023 Update) An article in the September 2019 issue of IEEE Spectrum claimed that silicon interconnect fabric, a method for connecting chiplets on a multichip module or advanced package, would eliminate PCBs and bulky SoCs for many applications, specifically motherboards. It's now 2023, and no one seems to have ditched PCBs yet; the demand for PCBs remains as strong as ever and is still projected to grow at double-digit CAGR. This is despite the expected Read Article
Decoupling Capacitor and Bypass Placement Guidelines Decoupling Capacitor and Bypass Placement Guidelines Power integrity issues are often assessed from the power supply side, but examining IC output is equally crucial. Decoupling and bypass capacitors help stabilize power fluctuations on the PDN, ensuring consistent signal levels and maintaining a steady voltage at an IC’s power and ground pins. To assist with effective usage, we've outlined essential design guidelines for bypassing and decoupling capacitors in your next PCB. This blog explores the Read Article
PCB Design and Layout for Hyperspectral Imaging Systems PCB Design for Hyperspectral Sensor and Imaging Systems What was once confined to the most advanced aerospace applications is now commonplace enough to be found in our everyday lives. Insulation, CCDs, air purifiers, and other technologies wouldn’t be possible without a robust space program in the 1960s and 1970s. One less well-known technology that deserves such attention is remote sensing, which has been used casually and for scientific research since the first American and Russian space flights Read Article
NB-IoT Antenna Design and Layout for Your PCB NB-IoT Antenna Design and Layout for Your PCB With all the possible wireless communication protocols available for use in a mobile device, it can be difficult to keep them straight. Narrowband IoT (NB-IoT) and LTE-M are two low-bandwidth protocols that provide remote monitoring capabilities over several miles of distance. While the data rates are quite low in both protocols, these protocols are excellent choices for lightweight embedded systems, such as small sensor arrays, industrial or Read Article
Single-Ended Switching Versus Differential Signaling Single-Ended Signal vs Differential Transmission Just about every place you look these days when you talk about high-speed PCB design, the signaling required for a product is, by default, differential signaling. But, differential signaling was not always at the forefront of product development. The original method of moving data was single-ended signaling. And, in some instances, it is still in use today. This article will describe the differences between single-ended vs differential Read Article
With so many possible noise sources, it can be difficult to tell them apart. Is it Simultaneous Switching Noise or Crosstalk? How can you distinguish simultaneous switching noise and crosstalk? Take a look at the difference between these two signal integrity problems in this article. Read Article
