There are many variants of USB on the market today, ranging from variations of the protocol itself to variations within the protocol. In this article, we’ll be examining the ULPI (UTMI+ low pin interface) interface, which can be found in USB high speed (HS) PHYs. In comparison to the UTMI+ specification and interface, as the name implies, ULPI is a low pin-count variation of this bus. This helps us as PCB design engineers, as we do not need...

Let’s build a DIY differential oscilloscope probe! Sure, I could buy one, but where is the fun in that? I’m working on a big project that will require an LC Tank circuit to be tuned, this tank circuit simulates to have voltages exceeding 1000v peak to peak. Furthermore, the point I need to measure the voltage is across a capacitor, with neither side being earth ground referenced. This rules out simply using a high-voltage oscilloscope probe to...

Designers often view component creation as a "necessary evil." It's something we all have to do at some point. But instead of spending hours creating your components, you can streamline the process. Altium Designer provides a wide range of tools to create different aspects of a component, including symbols, footprints, 3D model parametric data, supply chain details, and more. Join our webinar to discover how you can: Create Schematic symbols...

Our guest Phil Marcoux is very well-known in the advanced electronic packaging community and currently working as a business mentor in the electronics industry.  Phil is labeled as the father of SMT by the IPC. He is a Charter member of SMT Council, granted the IPC President's Award, past owner of over 40 integrated circuit packaging and camera module-related patents, and consultant on numerous heterogeneous designs and standards, just to name a...

SMD components require precisely sized pads for soldering during assembly. PCB designers still have to create many of their footprints using information from data sheets along with general pad and land size formulas. The designer is responsible for ensuring pad sizes are correct, either by calculating them and comparing with footprint data, looking through datasheets, or by memorizing SMD pad size standards. If you have a component and you don't...
