The jitter is dependent upon the configuration file you select for your application. So accordingly we have different datasheets for different configurations. Jitter is largely dependent on the output frequency. For non-spread outputs, the period jitter is around 185pS pk-pk. That makes the RMS value about 65pS. Our generic datasheet that can be downloaded from the latest version of InstaClock software installed on your computer contains the peak to peak period jitter value specified to be a maximum of 350ps.
