Why PCB controls 50 ohm impedance
single-ended network in the design is generally controlled by 50 ohms, so many people will ask, why is it required to be controlled by 50 ohms instead of 25 ohms or 80 ohms? First of all, 50 ohms is selected by default, and everyone in the industry accepts this value. Generally speaking, it must be a standard set by a recognized organization, and everyone designs according to the standard.
Using the reference clock to realize serial communication data recovery of Cyclone10LP devices
In the non-source synchronous low-speed serial data communication scenario, the clock frequency of the communication counterpart may be biased, which may cause the data receiving end to be unable to accurately sample. In this case, the SOFT-CDR and DPA functions in the high-speed transceiver or LVDS serdes of high-end Altera devices can effectively solve this problem.
CR2032 vs CR2450 batteries: Which one is better for your device?
Many daily devices use CR2032 and CR2450 batteries because of their small size and reliable performance.

What is Transistor hFE
hFE, also known as current gain or β (Beta), is an important parameter of the transistor, which represents the ratio between the base current and the collector current. It describes the gain capability of a transistor when amplifying current.
IGBT vs. MOSFET: A Comprehensive Comparison of Features
Both IGBTs and MOSFETs are important semiconductor devices that are widely used in power electronics, switching power supplies, and other high-power control systems. They can both be used to control the flow of current, but their operating principles, characteristics, and application scenarios differ.
WiFi 7 vs WiFi 6: Wireless Network Routing Comparison
WiFi 7 (802.11be) and WiFi 6 (802.11ax) are both wireless network communications standards, but they have significant differences in performance, spectral efficiency, latency, and the number of devices they support.
ENIG vs ENEPIG PCB: Explore the Difference
The choice of PCB surface finish is more than just a detail; it determines the performance and lifespan of the PCB. The versatile and robust Electroless Nickel Electroless Palladium Immersion Gold (ENEPIG) and the reliable and classic Electroless Nickel Immersion Gold (ENIG).
The automotive crystal oscillator FA-238A is the preferred choice for car Bluetooth

What are the differences between tantalum capacitors and ordinary capacitors
Tantalum capacitors are often used in high-precision circuits due to their high reliability, stability and small size, but due to their high price and polarity requirements, special attention should be paid to the connection polarity during design.
What is a clamping diode? Principle, function and application analysis
Clamping diodes are a common electronic component, also known as protection diodes or baropendulum diodes.
Four Common Topological Approaches to Powering LEDs
There are many topologies that can be used to power LEDs. As you probably already know, you need to first identify your design requirements before you start selecting, or you may end up with a design that is less than ideal or, worse, not guaranteed to work properly over the long term.
Regionalization Trend of Global Electronic Component Manufacturing: The Impact of Multinational Joint Ventures and Supply Chain Diversification
As global supply chain pressure increases, more and more electronic component companies are establishing production bases in places such as India and Southeast Asia, promoting the regionalization of supply chains.
US CHIPS Act 2024 in-depth implementation: How to reshape the global semiconductor supply chain and the future of technology
In August 2024, as the CHIPS Act is further promoted, the United States strives to localize the semiconductor industry and reduce external dependence. This strategic transformation is reshaping the global chip supply chain and is crucial to the future development of emerging technology fields such as AI and big data. This article deeply analyzes how the CHIPS Act reshapes the global supply chain and brings key industry impacts.
Hisense TVs sold out in Walmart on Black Friday
During this year's Black Friday promotion, Hisense TVs once again became a hot-selling product in the United States. Recently, a large number of videos of Americans rushing to buy Hisense TVs appeared on social media.
Hisense TVs sold out in Walmart on Black Friday
During this year's Black Friday promotion, Hisense TVs once again became a hot-selling product in the United States. Recently, a large number of videos of Americans rushing to buy Hisense TVs appeared on social media. On November 18, a netizen uploaded a video saying, "A Walmart store pushed out two piles with a forklift, and they were gone after they were sold out." The video shows that customers can't wait for the staff to tear open the packaging bags and have begun to buy them frantically. Many netizens also left messages in the comment area to post their orders and liked "Made in China".
Hisense has been deeply involved in ULED display technology. With its high cost-effectiveness and high quality, Hisense TVs have high discounts in major retailers such as Best Buy and Walmart, attracting a large number of consumers. The discounts on some models have even reached the lowest price in history, and the discounts on large-screen and high-end 4K TVs are particularly obvious.
This promotion is not accidental. In recent years, Hisense has further enhanced its brand influence through technological innovation and strategic expansion in the North American market, while taking into account the advantages of price and performance, becoming the first choice for many families to upgrade their entertainment equipment.
