The figure below shows an example of a phase noise plot for a 100 MHz MEMS oscillator (12 kHz to 20 MHz) from SiTime with 478 femtoseconds of integrated RMS phase noise.

This application note describes the common types of jitter encountered in high-speed systems and provides guidelines on how best to measure jitter.
- Period Jitter
- Cycle to Cycle Period Jitter
- Long Term Jitter
- Phase Jitter
