The STC3500, when configured for the appropriate stratum 3 bandwidth frequency, meets the stratum 3 requirements,

Jitter Generation – Jitter generation is the process whereby jitter appears at the output of a clock in the absence of input jitter.

The device jitter generation performance is as shown below:
