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.
