What Are Oscillator?
Oscillator products serve as frequency and time reference sources, setting them apart from crystal products that are often used for similar functions due to their added capabilities for maintaining and stabilizing the output. At their core, oscillators consist of a crystal or other resonant element, along with the necessary functions to provide a frequency reference without requiring extensive user intervention in the resonant element's operation. More sophisticated oscillators may include temperature compensation or control features, allowing for a more stable reference or one that can be selectively adjusted.
Performance Comparison for Oscillators
| Clock Source | Frequency | Accuracy | Advantages | Disadvantages |
| Quartz Crystal | 10 kHz to 100 MHz | Medium to High | Low Cost | Sensitive to EMI, vibration and humidity. |
| Crystal Oscillator Module | 10 kHz to 100 MHz | Medium to Extreme | Insensitive to EMI and Humidity. No additional components or matching issues | High cost, high power consumption, sensitive to vibration, large packaging |
| Ceramic Resonator | 100 kHz to 10 MHz | Medium | Lower Cost | Sensitive to EMI, vibration and humidity |
| Integrated Silicon Oscillator | 1 kHz to 170 MHz | Low to Medium | Insensitive to EMI, Vibration and humidity. Fast startup, small size, no additional components or matching issues | Temperature Sensitivity is worse than ceramic or crystal. High supply current. |
| MEMS Oscillator | Tens of kHz to Hundreds of MHz | Low to Extreme | Simple to design, Smaller packages, no external components, Can drive multiple loads. | Expensive |
| RC Oscillator | From Hz to 10 MHz | Very Low | Lowest Cost | Usually sensitive to EMI and humidity. Poor temperature and supply voltage rejection performance |
| LC Oscillator | from kHz to a hundred of MHz | Low | Low Cost | Usually sensitive to EMI and humidity.Poor temperature and supply voltage rejection performan |
