Hello everyone, I am Goat.I2C signals are a very common type of signal. It is a two-wire serial bidirectional bus used to connect microcontrollers and external devices. Because it only requires two pins (CLK and DATA), the hardware implementation is simple and highly scalable, making it widely used for communication between multiple integrated circuits ICs … Read more
In PCB (Printed Circuit Board) design, factors such as signal transmission stability and impedance matching are typically considered. Choosing the appropriate stacking scheme is crucial to meet design requirements. In certain cases, especially when designing six-layer boards, a special design scheme known as ‘pseudo eight-layer’ may be adopted. The ‘pseudo eight-layer’ actually refers to a … Read more
The Introspect MIPI D-PHY and C-PHY Analyzer is an ultra-portable high-performance instrument that supports characterization and validation of MIPI D-PHY and C-PHY transmitter ports on the same device. The analyzer operates at speeds of up to 8.5 Gbps for MIPI D-PHY and 6.5 Gsps for C-PHY, combining analog signal measurement capabilities with complex capture and … Read more
In a Profibus-DP network, the bus length is one of the key factors affecting system stability. As the bus length increases, signal attenuation, delay, and interference also increase, which changes the requirements for termination resistors. Today, we will discuss in detail how to correctly choose and install termination resistors for different lengths of Profibus-DP buses. … Read more
The RS-485 bus is widely used in industrial environments, which may experience high levels of electrostatic or surge interference. Engineers typically use gas discharge tubes and TVS diodes to build protective circuits. However, these circuits have a high junction capacitance, which, if improperly applied, can affect communication. This article will introduce a low junction capacitance … Read more
The RS-485 bus has advantages such as a simple structure and low cost. However, when engineers set up RS-485 bus networks, they often encounter the question: should termination resistors be added to improve the reliability of the entire network’s communication? This article will answer that question. 1. The Role of Termination Resistors For the RS-485 … Read more
