The automobile industry, a hotbed of innovation since the first motor vehicles hit the roads, has significantly evolved in recent years. This evolution, particularly in automotive Ethernet, is crucial for the industry's progress. Today's cars boasta plethora of features, including autonomous and semi-autonomous driving capabilities, automatic emergency braking, lane departure warning, Omni-View systems (surround-view system, Bird's eye system, etc.)  thateliminateblind spots, and a highly interactive and intuitive infotainment system. These innovations rely on a network of advanced cameras and sensors like radar, lidar, or image sensors to collect comprehensive information about the vehicle's physical environment. This data is then seamlessly conveyed to the driver through the dashboard display, alleviating their workload across various driving scenarios.

Picture bustling factories filled not with massive, outdated machines but with streamlined, efficient counterparts: robots darting around, intricate sensors overseeing every process, and data seamlessly flowing for real-time control. To tackle the challenges posed by critical industrial environments, engineers actively seek integrated circuits (ICs) housed in semiconductor packages known for their resilience and reliability. These packages must demonstrate exceptional thermal and mechanical durability and robust electrical performance under demanding conditions, ensuring optimal functionality and prolonged system life.

Surveillance cameras have become ubiquitous in today's world. Whether we're taking a morning jog in the neighborhood, escorting our children to school or commuting to work, chances are security cameras are monitoring us. Americans are captured on security cameras about 238 times weekly. The widespread adoption of security cameras on both private and public properties is on the rise, primarily due to ease of installation and the sense of safety they offer. Once set up, cameras promptly begin recording images and videos, allowing authorized users to access real-time video feeds over the internet via smartphones or other devices.

Today's automobile stands at the forefront of technological advancement with a vast array of sophisticated functions such as self-driving capability, GPS navigation, hands-free phone operation via Bluetooth further enhanced by Apple CarPlay^TM and Android Auto^TM along with many cutting-edge features that improve safety and comfort. The more features are added to an automobile, the more semiconductor components are used. The semiconductor components employed in automotive applications must satisfy the qualification criteria outlined in AEC-Q standards. This international standard specifies the qualifications necessary for packaged integrated circuits and discrete devices utilized in in-vehicle electronic systems. As more interfaces are used for high-speed signal transmission, more semiconductor components are added to automotive systems.

汽车接口的 ESD 防护

物联网的应用和 ESD 防护的重要性

物联网 (IoT) 是一个由嵌入传感器、软件和其他技术的物理设备组成的网络，用于通过互联网与其他设备和系统连接和交换数据。它与云服务器或网关共享数据以进行分析并采取相应的操作（图 1）。物联网的一大应用领域是农业。灌溉水量和时间是根据物联网传感器决定的，这些传感器收集土壤水分含量、养分、肥料用量和天气信息，帮助农户做出明智的决策，防止资源浪费。物联网在制造和工业自动化领域的应用也变得非常流行，从工厂车间、百货商店、跟踪机器性能、测量产品质量、资产跟踪到实时定位系统，不一而足。在智能家居自动化领域中，基于物联网的系统使我们的房屋更安全、更易于维护。

The Importance of Keyboard ESD Protection

自计算机问世以来，键盘一直是人类和机器之间沟通的主要渠道。多年来，许多技术和界面都发生了变化，但键盘在形式和功能上几乎没有变化。最近，我买了一款高档的无线键盘。最初，它通过蓝牙与计算机通信，没有任何问题。然而，大约一个月后，它突然不能用了。打开内部电路时，我惊讶地发现按键没有静电放电 (ESD) 防护。任何电子设备的键盘、侧键或按钮都容易受到 ESD 的影响，因为用户经常与它们互动。在键盘/小键盘/侧键中添加 ESD 防护装置，可以避免键盘故障等灾难性情况。我们来大致探讨一下 ESD 以及如何保护电子设备免受其影响。

无论您是在体育场的巨型屏幕上观看棒球比赛的动作回放、在大屏幕电视上观看电影，还是在笔记本电脑上播放视频，都期望获得高质量的视听 (AV) 体验。超高清串行数字接口 (UHD-SDI) 和高清多媒体接口 (HDMI) 是数字 AV 传输的两个标准。UHD-SDI 对通过同轴电缆或光纤传输未压缩和未加密的数字 AV 信号加以标准化。HDMI 是一种数字接口，用于将高清、高速数字多轨音频和未压缩视频信号从 HDMI 兼容源传输到视听显示器。尽管二者都可以将超高清 AV 信号从信号源传输到显示器，但 HDMI 更适合连接电脑、游戏机、蓝光/DVD 播放器、电视、投影仪等消费电子产品。 UHD-SDI 是专业室内/室外视频制作和电视广播等高端应用的首选，因为它支持远距离传输，并借助电缆两端的物理锁定机制实现可靠连接。UHD-SDI 同轴电缆可以将信号传输远达 300 英尺，而 HDMI 电缆即使在 50 英尺以内也会出现信号过渡衰减的问题。这两种接口可以通过 HDMI-SDI 或 SDI-HDMI 转换器一起使用。例如，如图 1 所示，HDMI 显示器用于 SDI 流的置信度监控，从而无需使用经过专门校准的 SDI 专用显示器。

不久之前，我唯一的健身追踪器是口袋里的一个计步器，用来测量我每天的步数。此后，情况发生了非常迅速的变化。现在，我手上戴有智能手表，可以追踪我的日常活动，包括完成的步数、行走的距离、消耗的卡路里、心率和呼吸模式。我还可以通过智能手表接收短信提醒、接听电话、收听我最喜欢的播客、查看天气。所有这些都是查看准确时间之外的附加功能。由于所有这些创新功能，佩戴智能手表并将其用作健身追踪器已成为全球注重健康人群的趋势。虽然这些可穿戴设备可以帮助人们保持健康，但制造商需要格外小心，保护这些可穿戴设备免受佩戴者身体产生的电气过载（EOS）和静电放电（ESD）的影响。
