Win a Backpack! How Hard Is It? Give It a Try! →_→ Long Press Recognition Each transceiver has an independent transmitter, which consists of PMA (Physical Media Attachment) and PCS (Physical Coding Sublayer). The PMA sublayer includes circuits for high-speed serialization/deserialization (Serdes), pre/post-emphasis, receive equalization, clock generation, and clock recovery. The PCS sublayer includes circuits … Read more

According to industry experts such as PROCENTEC, applications based on RS-485 fieldbus technology (PROFIBUS®) are continuously growing, and industrial Ethernet (PROFINET) applications are also rapidly increasing. In 2018, a total of 61 million PROFIBUS fieldbus nodes were installed globally, with a 7% year-on-year growth in PROFIBUS process automation (PA) devices. The installation base for PROFINET … Read more
Both CAN and RS-485 are commonly used field buses in industrial communication, and engineers are likely very familiar with bus isolation solutions. However, they may encounter situations where communication is abnormal even with an isolation scheme in place. This article will explore how to ground after bus isolation. Introduction To ensure the stability of communication … Read more

1 Introduction CAN stands for Controller Area Network, which is a serial communication network capable of achieving distributed real-time control. Advantages: The transmission speed can reach up to 1 Mbps, with a maximum communication distance of 10 km, a lossless arbitration mechanism, and a multi-master structure. In recent years, the price of CAN controllers has … Read more
As TI employees, we are often asked if there are any insights or tips we have when designing with RS-485. To this end, we have compiled a series of comprehensive tips that must be remembered when using RS-485. And usage methods…… 1) Use twisted pair cables with Zo = 120Ω or 100Ω 2) Connect bus … Read more
The ECU, short for Electronic Control Unit, refers to all electronic control systems in a car. With the increasing number of electronic components in new energy and autonomous vehicles, the wiring has become more complex. Currently, data exchange between multiple ECUs in a vehicle is connected via the CAN bus, forming a network system for … Read more
