Domestic Substitution, Independent Control: The Rise of China-Made Crystal Oscillators

2025-03-31

November 6, 2024 – Donald Trump re-elected as the 47th U.S. President

The Trump administration’s restrictions on Chinese tech firms like Huawei have impacted China’s advancements in 5G, semiconductors, and other critical technologies, accelerating the push for self-reliance in innovation.

With the rapid development of China’s information technology and high-tech industries, achieving independent control and domestic production of key components has become a strategic priority. Crystal oscillators (XO), as core components in electronic devices, provide stable frequency sources for communication, navigation, and computing systems. However, high-end oscillator technologies have long been dominated by foreign players, while domestic capabilities in high precision, anti-interference, and high-temperature resilience remained limited. This reality has driven China to pursue breakthroughs in fully localized oscillator production.

HangJing, a leading domestic oscillator manufacturer, has made significant progress in high-frequency stability, shock resistance, and durability through independent R&D. For instance, its oscillators are now widely adopted in edge computing, 5G base stations, and satellite navigation, meeting stringent military-grade requirements. Their vibration/acceleration-resistant designs are deployed in aerospace and defense applications, supporting China’s high-end equipment localization.

By advancing 100% China-made oscillators, HangJing reduces reliance on foreign suppliers while upgrading China’s electronics supply chain. This ensures core technology sovereignty and fosters long-term growth in critical fields.
