YXC（YQM), headquartered in China Shenzhen, is both the manufacturer and supplier mainly focusing on frequency components. Having been professional in crystal oscillators for 36 years. Trader turns into manufacturer. Cheap and bulky parts upgrade into highly precise ones. The small workshop with less experience grows into a high-tech enterprise with huge R&D team. We are constantly changing and expanding, but our goal to present the best products to the world is immutable. YXC has been moving towards automation on the basis of traditional quartz crystal oscillators process, YXC also has concentrated on R&D, will release new products from time to time. As YXC’s core product, the programmable crystal oscillator has applied for a number of patents and won the National Science and Technology Innovation Award YXC has silicon and quartz, differential, and voltage control programming oscillator. Parameters like frequency and voltage can be programmed. Frequency can be programmed up to 1.5GHZ which can meet any requirements of global customers and has achieved large-scale production. IC is the core of active crystal oscillators, YXC is also actively researching and developing and has already realized product applications.
