FAQ
Q1: What is the impact of temperature on crystal oscillators?
A: Temperature induces variations in frequency stability-often called drift. To counteract this, temperature-compensated (TCXO) and oven-controlled (OCXO) oscillators are engineered to reduce such effects across wide temperature ranges.
Q2: What is the significance of the "aging" parameter?
A: Aging measures long-term frequency drift stemming from gradual material changes in oscillator components. High-precision devices like OCXOs exhibit exceptionally low aging rates (e.g., ≤±1ppm/year), which is vital for applications needing consistent accuracy over time.
