April 13 to 16, 2025, Shenzhen Jingguanghua Electronics Co., Ltd. successfully participated in the HKTDC Hong Kong Electronics Fair (Spring Edition), held in Hong Kong, China. The company showcased its latest crystal components and customized frequency solutions, attracting strong interest from buyers across Australia, Germany, Russia, and India.   Jingguanghua Electronics is a professional manufacturer specializing in crystal oscillators, crystal resonators, temperature-compensated crystal oscillators (TCXOs), voltage-controlled crystal oscillators (VCXOs), and customized frequency modules. With advanced manufacturing facilities and a dedicated R&D team, our products serve a wide range of applications including telecommunications, industrial control, consumer electronics, and IoT devices, providing global clients with stable and reliable frequency control solutions. At this year’s show, Jingguanghua focused on exhibiting the following key product lines: l SMD Quartz Crystal Oscillators – Offering high stability and low phase noise, ideal for telecommunications and industrial applications; l 32.768kHz Clock Crystals – Compact and precise, widely used in portable and wearable electronic devices; l Customized Frequency Modules – Flexible frequency and package customization tailored to customer-specific requirements.   During the exhibition, the Jingguanghua booth attracted considerable attention, particularly for its ultra-compact SMD packages and W-series wide-temperature TCXO, which were praised by international buyers for their excellent performance and competitive pricing.   “We are sincerely grateful for the support and interest shown by clients from around the world,” said the General Manager of Jingguanghua Electronics. “This exhibition has not only strengthened relationships with our long-term partners but also opened new doors for global collaboration. Moving forward, we will continue to uphold our commitment to quality and innovation, and strive to serve a broader international market.”  

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. As consumer electronics evolve, so do we. Contact us for tailored support with your timing challenges.

6G communication technology is considered a major breakthrough for future networks, promising ultra-high speeds, ultra-low latency, and wider connectivity. However, the journey towards 6G faces numerous technical challenges, particularly in the field of high-frequency crystal oscillator technology.   The Prospects and Challenges of 6G Communication It is expected that 6G communication will begin deployment around 2029 or 2030, profoundly impacting the global network landscape. Compared to 5G, 6G will achieve higher spectrum efficiency, significantly enhance network capacity, and become the core support for building intelligent societies. Efficient high-frequency signal transmission will play a critical role in this process. However, as communication frequencies continue to rise, existing crystal oscillator technologies are increasingly showing limitations in stability, precision, and power consumption.   Challenges of High-Frequency Crystal Oscillators Frequency Stability and Precision 6G communication imposes stringent requirements on crystal oscillators. When operating at high frequencies, current technologies struggle to maintain stable frequency output and high precision in complex or extreme environments, which limits the performance potential of 6G communication. Balancing Power Consumption and Efficiency In dense network environments, the power consumption of high-frequency crystal oscillators becomes a key challenge for enhancing 6G performance. Finding a balance between maintaining high performance while reducing power consumption is an urgent task for technological innovation. Signal Generation and Control As communication frequencies continue to increase, efficiently generating high-frequency signals and precisely controlling them remains a significant technological hurdle.   Shenzhen Jing Guang Hua Electronics Co., Ltd. in the field of crystal oscillator cultivation Shenzhen Jinguanghua Electronics Co., Ltd.
