In many ways, electronic products resemble living organisms. For ex-ample, they have a central brain that might be a very simple 8-bit MCU or an extremely complex, mul-ticore SoC. Their circulatory system flows with electric charge rather than liquid, and enclosures provide a skeletal structure for support and protection. They even have a heartbeat, typically driven by a crystal or crystalrnoscillator. Although often overlooked during design, these timing sources are critical for the reliable operation of electronic devices. In this article, we'll explore the evolution of quartz timing technology across the years and how innovative changes have enabled us to develop the high-frequency systems that proliferate throughout our world too.
