Hello, Welcome to the Altium Learning Hub

Many design guidelines, which were perfectly applicable 10-20 years ago, hold to the same mantra around high speed signals: pick a single frequency to use for you calculations, and design to that frequency. For lower edge rates, this was usually fine because deviations from typical low-frequency values simply aren’t noticed. Modern computer interfaces and common high speed signaling standards used in embedded systems require a better approach...

Many Serial Communication Protocols are available for transferring data between electronic devices, whether that’s a microcontroller reading data from a sensor or sending data to a storage device. This is one of a series of articles that will cover some of the more popular protocols in common usage. We’ll complete the series with a comparison of the advantages and disadvantages of each. My aim is that the series will prove to be a useful...

In this next installment in our series on serial communications protocols, we’re looking at the popular I2C protocol. This follows on from the preceding articles where we are looking at some of the different types of Serial Communication Protocols available. These provide a practical solution to the transfer of data between devices over reasonably short distances. Typical applications include the capture of large amounts of data from data...

Working between the Electronic and Mechanical design domains brings unique challenges. ECAD and MCAD tools have different design objectives and have evolved down different paths, and so has the way they store and manage their design and project data.  Today's designs of small and complex product enclosures that house multiple, irregular-shaped and even flexible printed circuit boards (PCB), demand that this challenge be solved . To successfully...

In this next article in our series that is looking at different types of Serial Communication Protocols, we will be looking at the popular SPI protocols. This is one of many popular protocols in common usage that we will be looking at. We will provide a useful summary of each type’s advantages and disadvantages at the end of this series. SPI stands for Serial Peripheral Interface. It is a serial communication bus commonly used for short-distance...

A heavy focus is usually put on managing your design data, but what about managing your design team? A mismanaged design team can lead to a disorganized and inaccurate design library and data. Duplicate parts, incomplete components, unauthorized design release, these are all common occurrences when dealing with a mismanaged team. Watch this video to to see how Altium 365 can help you: Organize users into access restricted groups Manage...

Power supplies and regulators can come in all shapes and sizes. While they are normally discussed as different products, they are equivalent electrically, particularly switching regulators. From a high-level system perspective, the switching regulator section in a power supply and the actual regulator circuit perform the same functions within the same block diagram. For a power supply, it’s simply a matter of scale and how the regulator...
