WebOct 29, 2024 · A crystal oscillator stability is measured in ppm (parts per million), and stability could be somewhere around 0.01% to 0.0001% over -20 to +70 Celsius, depending on the specific device. An RC oscillator's stability can at best be 0.1% and LC 0.01%, they are more typically around 2% and are very sensitive to temperature changes. WebThe third noise source is the oscillator circuit, where the oscillator swings rail to rail. In addition to the fundamental freq uency, harmonics are introduced on the output side because the output buffer is digital, which squares the sine wave. Also, any noise caused by internal operations, such as the clock buffers, appears on the output. WebJul 9, 2024 · The crystal oscillator startup time may be degraded by selecting a crystal blank with a high value of ESR and/or a high value of required crystal load capacitance.
