The Impact of Crystal Oscillator Stability on Signal Integrity
Mobile phone crystal oscillator stability is crucial for maintaining signal integrity in communication systems. Stability refers to the oscillator's ability to maintain a consistent frequency over time, despite environmental changes such as temperature fluctuations, aging, and power supply variations. High stability ensures that the signal remains within its specified frequency range, minimizing phase noise and jitter, which are critical for high-speed data transmission and error-free communication.
