Introduction:
Quartz oscillators are electronic circuits based on an oscillating quartz crystal to generate a highly stable frequency. Depending on the requirements and environmental conditions, frequency stabilities in the range of 10E-5 to 10E-12 per day can be achieved. Standardised oscillator modules are available for everyday applications, while high-precision oscillators are usually designed and manufactured individually for special requirements.
Oscillator types:
According to international standards, crystal oscillators are divided into the following categories:
- SPXO - Simple Package Crystal Oscillators
- VCXO - Voltage Controlled Crystal Oscillator
- TCXO - Temperature Compensated Crystal Oscillator
- OCXO - Temperature Stabilised Crystal Oscillators (Oven Controlled Crystal Oscillator)
- LPXO - Low Power Crystal Oscillators with temperature stabilities from ±0.5ppm above -40/+85°C and with an ageing of ±1x10E-6.
