A crystal oscillator is an electronic component that operates based on the piezoelectric effect. It generates stable and high-precision clock signals. Crystal oscillators are widely used in various instruments and measurement systems to provide accurate time references and timing control, ensuring the efficient and stable operation of devices. Common types of crystal oscillators include quartz crystal oscillator, temperature-compensated crystal oscillators (TCXO), and oven-controlled crystal oscillators (OCXO).
The following table summarizes the role of crystal oscillator and its key performance requirements in several representative instruments:
| Instrument Type | Role of Crystal Oscillator | Key Performance Requirements |
|---|---|---|
| Smart Meters | Data collection, communication synchronization, RTC timing | Low power consumption, high stability |
| Electronic Clocks | Provides precise timebase, long-term timekeeping | High frequency accuracy, temperature stability |
| Electronic Scales | Processor reference frequency, improving weighing accuracy | Fast startup, high frequency stability |
| Infrared Thermometers | MCU timing control, data processing synchronization | Small package, low power, stable frequency |
| Microscopes | Controls imaging timing, supports module coordination | High frequency stability, anti-interference |
| Breath Alcohol Testers | Drives signal acquisition, supports communication modules | High accuracy, strong reliability |
As shown in these typical applications, crystal oscillator plays a central role in various electronic measuring devices as the "time hub" being an indispensable part of ensuring the normal operation of system functions.
As instrumentation advances towards higher speeds and precision, the requirements for system clock sources are becoming increasingly stringent. Specifically, in devices such as high-speed sampling oscilloscopes, spectrum analyzers, and high-end digital multimeters, factors like the phase noise, jitter performance, and long-term stability of the crystal oscillator's frequency directly determine the measurement accuracy and instrument reliability.
Spectrum Analyzers: Require ultra-low phase noise crystal oscillator to avoid increasing signal background noise.
Precision Measurement Instruments: Need high-temperature stability to ensure measurement consistency in experimental environments.
