7. Silicon Controlled RectifierSilicon controlled rectifiers are an essential component of circuit boards, which is why enthusiasts love to use them. They are also referred to as thyristors because they are very similar to diodes and transistors. They consist of four layers of silicon and have only three terminals; they are not used as amplifiers … Read more
RTC Crystal Oscillator Introduction to RTC RTC, which stands for Real-time Clock, is an electronic device that outputs the actual time like a clock. It is generally an integrated circuit, hence also referred to as a clock chip. Real-time clock chips are among the most widely used consumer electronic products in daily life. They provide … Read more
These two capacitors are called the load capacitors of the crystal oscillator, connected to the two pins of the oscillator and to ground, typically in the range of tens of picofarads. They affect the resonant frequency and output amplitude of the oscillator, and the supplier usually asks for the load capacitance when ordering the crystal … Read more
HLC Huillong| Manufacturer of High-Precision Quartz Crystal Components In the era of the Internet of Things (IoT), billions of devices require seamless communication and collaboration. The foundation of all this is the precise clock signals provided by small crystal oscillators—they act as the “heartbeat” of the IoT world, providing accurate time references for data exchange … Read more
1. Problem Description A certain dashcam requires an external adapter for testing. During power-on testing, it was found to exceed standards, specifically at frequencies of 84MHz, 144MHz, and 168MHz. The cause of the excessive radiation needs to be analyzed, and corresponding countermeasures should be provided. The radiation test data is as follows:2. Analysis of Radiation … Read more

Among all device characteristics, noise can be a particularly challenging and difficult design topic.This article mainly discusses the impact of clock noise on high-speed DAC phase noise. Sources of DAC Phase Noise For high-speed DACs, phase noise primarily comes from the following aspects: clock noise, power supply noise, as well as internal noise and interface … Read more
Before we begin: 1. This article will focus on Microchip’s products. I believe Microchip has the most articles on clocks among MCU companies. The terminology used by Microchip may differ from that of other companies, but the usage is the same and does not affect understanding. 2. The term “clock source” is used to distinguish … Read more
Power Supply: If the microcontroller is having issues, first check the power supply. There may be a problem with the power supply. Use a multimeter to check the power supply voltage of the microcontroller; it is best to use an oscilloscope to capture the voltage waveform because the voltage may be unstable (for example, voltage … Read more
