At present, the market share of crystal resonators is more than half, and the Internet of Things has spawned industry demand. The timing oscillator is a frequency control element made of the piezoelectric effect of the timing crystal, which provides a reference frequency signal for the microchip, and its downstream application field is electronic products. Time-dependent crystal oscillators can be divided into crystal oscillators (active crystal oscillators) and crystal resonators (passive crystal oscillators) according to their properties. In terms of structure, an active crystal oscillator is usually a collection of circuit gates amplified by a crystal resonator oscillation circuit, which has higher accuracy and stability than a passive crystal oscillator. In the manufacturing process, the main difference between the crystal oscillator and the resonator is the multi-IC winding and wire bonding process of the crystal oscillator. From a market perspective, according to data from CSA and others, the global market size of Yingshi Jingzhen in 2019 was US$3.041 billion, with shipments of 18.068 billion units. In 2019, crystal resonator sales accounted for the highest proportion of 58%, and sales accounted for 90.01%. The total revenue of the world's top ten manufacturers in 2019 was US$1.939 billion, accounting for 63.8%. Crystal Technology ranks third and has the first growth rate in 2019. According to the forecast of the "Ericsson Mobile Market Report", the number of global IoT devices will increase to 26.9 billion in 2026. If the average number of crystal oscillators for each IoT device is estimated to be 5 to 10, there will be a market size of nearly 134.5 to 269 billion in the next few years. The Internet of Things and smart phones will cause continuous high demand for crystal oscillators. .

    The technology started early and continued to lead, with mainland manufacturers closely following domestic substitution. Jingtaijing Technology, Huilun Crystal and Jingsai Technology account for more than 85% of the revenue from crystal oscillator related businesses. From the perspective of the production, sales, and purchase systems of various companies, Jinko Technology has developed earlier and has obvious advantages, while mainland manufacturers have strengthened their competitiveness in different directions.

    Judging from the main products of major manufacturers, major manufacturers have arranged MHz crystal resonators and thermal TSXs. The main products of Taijing Technology include various resonators and temperature-compensated TCXOs. Huilun Technology has MHz crystal resonator, TSX and temperature compensated TCXO, Jingsai Technology has MHz crystal resonator, TSX and ordinary oscillator. In terms of development layout, Jinko Technology continues to deploy 5G175WiFi 6 and so on. Taijing, Huilun, and Crystal Competition continued to give play to their respective advantages.
