The demand for compact, accurate position sensors in automotive applications will grow substantially to $1.6 billion by 2026, in line with the growth in electric vehicles (Figure 1). These sensors track the rotor’s position inside the motor responsible for traction, power steering, and windows; ensuring control and safety coverage.
The I²C two-wire bus is still as popular today as when Philips originally invented it in 1982. Initially operating at 100KHz, the latest incarnation, version 7 (2021) Ultra-Fast-mode (UFm), now clocks at 5MHz—making it fast enough for most medium-speed peripherals, including digital I/O, GPIO, keyboards, keypads, and sensors.
USB, USB Type-C®, and DisplayPort™ (DP) cables have become so ubiquitous as to even be purchased in low-cost convenience stores. However, while two individual cables may appear identical to the naked eye, they can differ considerably in the quality of performance they provide. Low cost can mean low quality, and alongside instances where cheap cables have caused electronic equipment to malfunction or have corrupted data, they typically cause poor picture quality or slow down the rate of data transfer to well below the multi-gigabit bandwidth offered by the latest USB specification (USB 4).
In the not-too-distant past, it seemed like every electronic device had its own custom power supply, cable, and interface (Figure 1). USB Type-C® (or USB-C®), which implements the USB power delivery (USB-PD) specification, was supposed to solve this problem by introducing a single standard interface that all devices could use.
Today’s PCIe 3.0 switches, which support data speeds up to 8GT/s per lane, combine generous bandwidth and up-to-the-minute power-management and RAS features to meet the needs of mobile and embedded applications.
壓電發聲器在許多產品應用中，用來產生警告或警示音，通常用於可攜式、電池供電和節省空間的產品。這些裝置由連接到金屬板上的陶瓷元件組成，對裝置施加電壓時，陶瓷元件產生的壓電效應，會讓金屬板變形。隨著電壓的變化，陶瓷元件會跟著收縮和膨脹，連接的金屬板也因此振動而發出聲響。
The automotive lighting market continues to grow strongly and is forecast by analyst Yolé to reach US$38.8 billion by 2024. Over the past few years, LEDs have taken an increasing share of this market, and LED exterior lights have become a familiar sight on our roads.
The global appetite for data shows no sign of abating and continues to place pressure on service providers to handle more bits, more quickly.
DC electric motors have been around for nearly two hundred years, with a steady series of refinements in that time. More recently, brushless DC motors have become increasingly popular but for many applications brushed DC motors are still the right choice.
在家裡或工作中遇到的大多數電子系統將包括至少一個振盪器作為時鐘工作，提供準確的定時，同步操作或作為頻率參考。在這裡，我們將看到使用石英晶體振盪器的許多好處，並討論可用的選擇。
