PIC18-Q71系列微控制器的移位寄存器使用信号路由端口

这篇博客文章介绍了集成到PIC18-Q71系列微控制器（MCU）和未来设备上的新信号路由端口（SRPORT）外设。我们将讨论如何将SRPORT与其它外设配合使用来实现串行输入并行输出（SIPO）移位寄存器。

了解问题

在I/O引脚有限的MCU中，引脚可用性通常成为主要的系统限制。通常在可用引脚的数量与芯片本身的成本、尺寸和复杂性之间存在权衡，这使得很难找到完美的平衡。涉及多个外设互连的应用经常会遇到并非所有外设信号都能直接互连的问题，需要通过外部I/O引脚路由信号才能建立连接。这可能并不理想，因为它限制了MCU在需要时与多个外部元件接口的能力，从而降低了系统的整体功能。

这种情况有解决方案，例如使用更高引脚数的石英晶体设备来确保所有连接都可以进行，或者添加额外的硬件（例如I/O扩展器）来增加可用的引脚数。尽管这些解决方案看似可行，但理解其中的利弊很重要，因为它们可能会增加系统的复杂性，从而增加总成本。

Quantic Wenzel Crystal, a leader in crystal oscillators, frequency sources, and integrated microwave assemblies has completed delivery of a space-qualified frequency synthesizer assembly for NASA’s Europa Clipper mission. Scheduled to launch next year, the spacecraft will orbit Jupiter to perform a detailed exploration of Europa – a moon that shows evidence for an ocean of liquid water beneath its icy crust and which could host conditions suitable for life.“Our support of the Europa Clipper mission is another exciting step in our work with JPL,” said Jigar Shah, Director of Business Development at Quantic Wenzel. “Wenzel is widely known as a company that RF engineers come to when they need to solve their unique frequency reference and timing challenges for space applications.”

In the realm of electronics, precision is paramount. The accuracy of a device's operation often hinges on the stability of its frequency generation.

Nature, like a quartz crystal, is essential in pursuing precision. Modern electronics use a quartz crystal found in nature as a crystal oscillator. This blog post will explain the process of how this happens.

Understanding Quartz and Its Unique Properties Quartz is one of the most abundant minerals found on Earth. It's a semi-precious gemstone composed of silicon dioxide. Quartz crystals come in various types, including rock crystal, amethyst, citrine, rose quartz, smoky quartz, ametrine, jasper, carnelian, and agate. Beyond its aesthetic appeal, quartz has unique properties, making it a cornerstone of electronic devices.
Applying mechanical stress to quartz generates an electric charge, and people call this property piezoelectricity. Crystal oscillators, which many devices use, rely on the special properties of quartz crystals.
The Transformation Process
Turning a piece of raw crystal quartz into a functional crystal oscillator involves several steps. We perform each step meticulously to ensure that the resultant oscillator functions with the highest possible precision.
Cutting and Grinding
Start by cutting and grinding the raw quartz crystal into a thin wafer. Typically, it takes the shape of a rectangle or a tuning fork. The cutting of quartz affects the stability of its frequency due to its crystal lattice. Once cut, the wafer is further ground and lapped to achieve the desired thickness and parallelism.
Mounting and Encasing
After shaping the quartz wafer, we mount it between two electrodes, usually made of metal. These electrodes are essential for applying the voltage that will cause the quartz to vibrate. The quartz and electrode assembly is protected from temperature and humidity to maintain frequency stability.
Testing and Adjustment
The encased quartz crystal is now a basic crystal oscillator. However, engineers must test it for precision before using it in an electronic device. If the oscillator's frequency is off, we may need to adjust the thickness of the quartz wafer slightly. This testing and adjustment process continues until the oscillator operates at the desired frequency with an acceptable level of stability.
The Role of Quartz Oscillators in Electronics
Quartz crystal oscillators have become indispensable in the world of electronics. When electricity powers the quartz crystal, it vibrates at its special frequency, generating a signal with an exact frequency. This signal stabilizes clock signals in digital circuits, stabilizes frequencies in radios, and keeps time in wristwatches.
Quartz oscillators are everywhere, so you're probably always close to one, within a few feet, at any time. They exist in everything from cell phones and computers to car engines and satellite systems.
In Conclusion
From raw quartz crystal to electronic components, the journey combines nature and technology in a captivating way. It's a testament to human ingenuity that we've found ways to harness the unique properties of quartz for our purposes.
We provide high-quality quartz crystal oscillators for different purposes . We are excited to be a part of this journey.
The accuracy of our products depends on the quality of the quartz crystal we use. It also depends on how carefully we make them. You can learn more about our commitment to quality and the role of quartz in our products here.
When you use your phone or drive your car, think about the small piece of quartz. This small piece of quartz helps these devices work accurately. From raw quartz crystal to an indispensable part of modern electronics, it's truly a transformation journey.
