As quantum computing makes rapid strides toward commercialization, global tech leaders are racing to lead the next era of computing. Behind the scenes of cutting-edge quantum chips, superconducting qubits, and entanglement algorithms, building a stable and reliable control and measurement system still depends on unsung support components — like crystal oscillators. In quantum systems, although the core relies on microwave cavities, laser controllers, and ultra-low-temperature cooling systems, the surrounding electronics still require precise timing control. As the primary timing source, crystal oscillators are widely used in data acquisition modules, control circuits, communication interfaces, and power management systems of quantum research equipment.   For instance, in a quantum laboratory’s microwave drive system, a Voltage-Controlled Crystal Oscillator (VCXO) can serve as a crucial reference source for frequency synthesis, ensuring phase stability in the excitation signals. During data acquisition, a Temperature-Compensated Crystal Oscillator (TCXO) can provide a steady sampling clock, minimizing drift caused by temperature variations and improving measurement accuracy.   At JGHC Crystal Oscillators, many of our customers — including advanced research institutes and electronics manufacturers — have requested customized solutions with low phase noise, wide temperature tolerance, or ultra-compact packaging. These needs reflect how traditional crystal technology is playing an essential role in the development of cutting-edge systems like quantum control hardware.   While crystal oscillators may not be the "stars" of quantum computing, they remain fundamental building blocks of any advanced technology system. The more complex the architecture, the greater the demand for stability and reliability at the component level. As quantum–classical hybrid architectures, high-performance computing platforms, and quantum communication hardware evolve, we believe that crystal oscillators will continue to provide precise timing — quietly supporting every technological leap. At JGHC, we remain committed to delivering high-precision, high-reliability timing solutions to power every moment of technological innovation.

As Industry 4.0 continues to advance, smart factories are emerging rapidly around the world. Automation, the Internet of Things (IoT), edge computing, and artificial intelligence are transforming manufacturing processes. At the heart of these innovations lies a tiny but vital component: the crystal oscillator. It plays a critical role in ensuring the precise and stable operation of smart factory systems.   Key Roles of Crystal Oscillators in Smart Factories Precise Synchronization and Stable Communication Smart factory devices such as robots, sensors, and control systems require highly accurate synchronization. Crystal oscillators provide stable and reliable frequency signals for clock modules, enabling seamless system coordination. For example, in industrial Ethernet and wireless communication modules, signal stability directly impacts data accuracy and real-time performance. Timing Sources in Edge Computing and Control Systems Crystal oscillators serve as the foundational clock sources in edge computing units and PLC controllers. Their frequency stability ensures accurate processing and swift system responses, making them essential for intelligent decision-making at the machine level. Reliable Operation of IoT Terminals IoT devices deployed throughout smart factories—such as temperature sensors, vibration monitors, and power meters—depend on high-precision crystal oscillators to drive their microcontrollers. These ensure accurate data acquisition and timely cloud reporting, enhancing factory responsiveness and automation. Driving Systems in Industrial Robots and Automation Equipment Industrial robots require high-frequency, low-jitter clock signals to precisely control servo motors and positioning systems. Temperature-compensated (TCXO) and voltage-controlled (VCXO) oscillators are especially suitable for these applications, maintaining excellent frequency stability even in harsh environments.   Why Choose JGHC Crystal Oscillators?

On April 19, 2025, in Beijing's Yizhuang district, the world witnessed a groundbreaking event: the first-ever humanoid robot half-marathon. As 21 robots from over 20 countries lined up alongside more than 12,000 human runners, a new benchmark was set for robotic mobility, autonomy, and endurance. But while the crowd marveled at their mechanical strides, few realized the invisible heartbeat behind every coordinated step—the crystal oscillator. Event Highlights Historic Milestone This was the world’s first marathon-style competition where humanoid robots raced side-by-side with human runners. Participating teams from Asia, Europe, and North America deployed robots equipped with sophisticated motion control systems and AI-powered navigation. Outstanding Performance The “Tiangong Ultra” robot finished first with a time of 2 hours and 40 minutes, setting an unofficial world record. Several other robots completed the race within three hours, while a few withdrew due to balance issues on turns—highlighting the real-world endurance challenges faced by mobile robotics. The Critical Role of Crystal Oscillators in Robotics  Precision Timing for Motion Control As the master clock within robotic systems, crystal oscillators provide jitter-free, stable pulse signals that synchronize servo motors and actuators across multiple joints. Even millisecond-level timing drift can result in unstable gaits or loss of balance on complex terrain. Stable Sampling for Sensor Modules High-frequency sensors such as IMUs, LiDARs, and camera modules rely on oscillator-generated timing signals for data timestamping. Maintaining a sampling rate of 100 Hz or higher is crucial for real-time balance correction and obstacle avoidance. Reliable Communication Channels Robotic systems equipped with onboard Wi-Fi and 5G modules utilize temperature-compensated crystal oscillators (TCXOs) to maintain stable carrier frequencies across a wide temperature range (–40 °C to +85 °C). This ensures robust, packet-loss-free communication between the robot and its control hub. Jingguanghua Electronics’ Specialized Frequency Solutions With over a decade of expertise in frequency control, Jingguanghua Electronics provides application-specific crystal oscillators tailored for robotics: High-Stability TCXOs Operate reliably between –40 °C and +85 °C, with frequency stability within ±0.5 ppm, ensuring consistent performance under temperature fluctuations.

In today’s fast-evolving consumer electronics industry, demands for compact size, low power consumption, and high precision are growing stronger. One recurring technical challenge is frequency matching, especially during the early design phase. For products like Bluetooth earphones, smart wearables, or micro remote controllers, standard crystal oscillator frequencies often fail to meet system-level requirements. Recently, JGHC Crystals received a request from a wearable electronics manufacturer in Shenzhen. Their Bluetooth audio module encountered unstable pairing and connection issues due to frequency drift caused by PCB layout constraints and internal MCU timing deviation. The standard 26MHz crystal they were using wasn’t stable enough under practical conditions. Our Engineering Solution: After a thorough circuit analysis and communication with their R&D team, our engineers identified a frequency deviation of around 2.1 ppm due to the main chip and external thermal fluctuation. The ±10 ppm standard crystal could no longer meet the strict timing tolerance of their Bluetooth protocol. We designed a custom crystal oscillator with the following specs: Frequency: 26.000150 MHz Accuracy: ±5 ppm (from -20℃ to +70℃) Package: 3.2x2.5mm Low startup voltage design The Result? Our custom solution led to a 23% improvement in Bluetooth connection stability. The first-time pairing success rate increased from 82% to over 96%. What the Client Said: We initially thought it was a firmware issue, but it turned out the crystal’s frequency deviation was the real problem. Huge thanks to JGHC for the fast and precise custom solution Conclusion At JGHC, we are committed to delivering high-precision, fully customizable, and mass-production-ready frequency solutions.
