Design Challenges of Electromagnetic Compatibility (EMC) in High-Speed DSP Systems

Design Challenges of Electromagnetic Compatibility (EMC) in High-Speed DSP Systems

With the increasing popularity of high-speed Digital Signal Processors (DSPs) and their peripherals, electronic system designers are facing increasingly severe issues related to electromagnetic interference (EMI). In earlier studies, such issues were often referred to as electromagnetic interference (EMI) or radio frequency interference (RFI), while modern engineering more accurately adopts the concept of “electromagnetic compatibility … Read more

Why Use Twisted Pair for CAN/RS-485 Communication

Why Use Twisted Pair for CAN/RS-485 Communication

In applications such as CAN and RS-485, it is generally recommended to use shielded twisted pair cables for networking and wiring to reduce external interference on bus communication. Many engineers understand this recommendation but do not know the underlying reasons. This article will briefly introduce the principle of interference resistance in twisted pair cables. 1Differential … Read more
