What is peak to peak and rms period jitter and what is cycle to cycle period jitter?
Period jitter is the measure in the time domain and is specified in picoseconds (pS). Peak to Peak and rms period jitter are commonly specified for non-modulated clock oscillators and are defined over a number of cycles. Due to the output frequency modulation, only cycle to cycle period jitter is specified on spread spectrum clock oscillators. Cycle to Cycle period jitter is measured in the time domain and is defined as the worst case clock period deviation of adjacent cycles.
