Application Characteristics and Industry Market Analysis of Active Crystal Oscillators in 2023
Active crystal oscillators, also known as quartz crystal oscillators, are complete resonant oscillators that include not only a quartz crystal but also transistors and resistive-capacitive components, resulting in a relatively larger size. They typically have four pins with the following common connections: pin 1 left unconnected, pin 2 grounded, pin 3 connected to the output, and pin 4 connected to the voltage supply.
Active crystal oscillators offer superior stability compared to passive crystal oscillators and are primarily used in precision measurement and wireless base stations. However, their signal voltage is fixed, requiring careful selection of the appropriate output voltage, which limits flexibility. Additionally, they are more expensive. Based on function and implementation technology, active crystal oscillators can be further classified into Temperature Compensated Crystal Oscillators (TCXO), Voltage Controlled Crystal Oscillators (VCXO), standard Crystal Oscillators (XO), and Oven Controlled Crystal Oscillators (OCXO).
Classification, Features, Applications, and Frequency Range of Active Crystal Oscillators
In addition to quartz crystals, active crystal oscillators require an integrated circuit, which can be simply understood as a combination of "passive crystal oscillator + IC." Currently, the precision of active crystal oscillators can reach ±0.1 ppm, primarily used in fields with specific precision requirements. With the development of various mid-to-high-end applications, the uses of active crystal oscillators have become increasingly widespread, and market demand continues to grow. In 2019, China's demand for active crystal oscillators increased from 6.22 billion units in 2015 to 10.82 billion units. In recent years, with a severe decline in consumer electronics market demand and terminal manufacturers and agents collectively adjusting inventories, market demand has slowed. It is estimated that China's demand for active crystal oscillators in 2023 will be approximately 16.55 billion units.
China's overall market for active crystal oscillators is still dominated by imports. In recent years, affected by IC shortages, the overall delivery cycle for active crystal oscillators in China has been long with tight supply, leading to a rising trend in market prices. It is estimated that the average market price of active crystal oscillators in China will be approximately 0.74 yuan per unit in 2023.
In 2015, the market size of active crystal oscillators in China was 3.632 billion yuan, reaching 5.464 billion yuan in 2019. It is projected that the market size of active crystal oscillators in China is expected to reach 12.204 billion yuan by 2023.
