With the rapid growth of renewable energy, energy storage systems, and smart grids, power conversion and inverter control have become the core of the modern energy ecosystem. Inverters must efficiently and stably convert DC power into AC power while maintaining precise synchronization with the grid. In this process, crystal oscillators play an irreplaceable role. Key roles of crystal oscillators in power conversion and inverter control include: Frequency Stability: Inverter control chips rely on crystal oscillators to provide accurate clock signals, ensuring the output AC frequency (50Hz/60Hz) matches the grid precisely. Phase Synchronization: For grid-connected operations, oscillators provide reference signals for phase detection and synchronization, preventing power quality issues or equipment damage. Data Communication: Within EMS and BMS, crystal oscillators ensure accurate timing for protocols such as CAN, RS485, and Ethernet, enabling efficient data exchange. Power Optimization: Oscillators support microcontrollers in achieving fast and stable PWM control, improving conversion efficiency and reducing energy loss. Future Trends As renewable energy and smart grid technologies continue to evolve, inverters and energy storage systems demand more advanced oscillator solutions: High-Precision TCXO/OCXO: Ensuring frequency stability under temperature variations and long-term operation. Wide-Temperature and High-Reliability Packages: Designed for outdoor and harsh environments. Low-Power Oscillators: Suitable for distributed energy storage and microgrid applications. Crystal oscillators are not only the “hidden cornerstone” of power conversion and inverter control but also a key enabler for the safe and efficient operation of future energy systems.

In the use of smart sports watches, users often face some frustrating issues: GPS drift: running tracks appear inaccurate or offset; Unstable Bluetooth: frequent disconnections with phones or earbuds; High power consumption: battery drains too fast, limiting usage time. These problems are not solely caused by software. A key factor lies in the crystal oscillator (XO) selection during hardware design. The Role of Crystal Oscillators Crystal oscillators serve as the precise clock source for the GPS module, Bluetooth chip, and MCU controller inside sports watches. For GPS: even a tiny clock error can lead to significant location drift. For Bluetooth: frequency deviation may cause connection loss or data errors. For power management: unstable clocks reduce efficiency in low-power modes, draining the battery faster. Root Causes of Common Issues Low-accuracy oscillators → large temperature drift, poor stability in varying environments Insufficient power optimization → faster battery drain. Lack of differential/temperature-compensated solutions → poor performance in outdoor environments.

In recent years, RISC-V, as an open Instruction Set Architecture (ISA), has been rapidly emerging and widely adopted in IoT, embedded systems, AIoT, edge computing, and high-performance computing. However, regardless of how advanced the processor architecture is, it relies on one essential component — the Crystal Oscillator. Providing a stable and precise clock signal, it acts as the "heartbeat" of the RISC-V platform. Role of Crystal Oscillators in RISC-V Systems System Clock Source The main operating frequency of a RISC-V processor is typically generated by a Phase-Locked Loop (PLL), with its reference signal provided by a crystal oscillator. Peripheral & Communication Clocking High-speed interfaces such as USB, Ethernet, SPI, and UART require precise clocks to ensure stable data transmission. Low-Power & Real-Time Clock Low-power RISC-V chips often use a 32.768 kHz crystal oscillator as the RTC time source, enabling timekeeping in standby mode. High-Speed Synchronization RISC-V SoCs with high-speed interfaces such as PCIe, MIPI, and SDIO require high-frequency crystal oscillators (e.g., 100 MHz, 125 MHz) for data link synchronization.

As IoT, smart manufacturing, automotive electronics, and medical devices continue to evolve, sensors have become the "sensory nerve" of intelligent systems. With growing demands for precision, miniaturization, and low power consumption, the requirements for frequency control components are also rising. Crystal oscillators play a fundamental role in sensor systems by delivering stable clock signals, which ensure accurate data acquisition, processing, and transmission.  In environmental sensors, they enable consistent sampling of temperature, humidity, and gas data. In medical devices, they support synchronized measurements such as heart rate or SpO2. In automotive radar and vision systems, oscillators are essential for high-speed communication and microsecond-level control. JGHC crystal oscillators are widely integrated into sensor applications such as: Smart environment monitoring (e.g., temperature, humidity, light, gas sensors) Medical and wearable health devices (ECG, blood pressure, oxygen sensors) Industrial automation (pressure, displacement, acceleration sensors) Intelligent vehicles (camera modules, radar, LIDAR) Smart infrastructure (noise detection, water quality sensing, etc.) To address diverse technical requirements, JGHC offers: 32.768kHz low-power crystals,  ideal for battery-powered and standby-mode sensors High-frequency SMD oscillators, for fast data processing and microcontroller systems High-temperature stability models, suitable for harsh industrial environments Miniature packages (e.g., 2.0x1.6mm), optimized for compact sensor designs Choosing a reliable crystal oscillator is critical to ensuring stable sensor performance.
