CRYSTAL (XTAL) OSCILLATOR WITH HIGH INTERFERENCE IMMUNITY

摘要

Systems and methods are provided for a crystal (xtal) oscillator with high interference immunity. Generated reference signals may be processed to mitigate effects of interference. The processing may comprise filtering, particularly at harmonic positions, to remove or greatly reduce interference signals.

1. A method comprising:
in a crystal oscillator that provides periodic signals for an electronic system associated with the crystal oscillator:
generating signals periodically based on resonance of a crystal core of the crystal oscillator, the generated signals having a particular resonant frequency; andprocessing the generated signals to mitigate effects of interference introduced by other operations and/or components of the electronic system, wherein the processing is configured based on the particular resonant frequency.
