Wander Transfer – Wander transfer is the degree to which input wander is attenuated (or amplified) from input to
output of a clock. The GR-1244 requirements for wander transfer limits are shown below.

The STC3800, 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:

Jitter Transfer – Jitter transfer is the degree to which input jitter is attenuated (or amplified) from input to output of a
clock. It is a function of the selected bandwidth. The STC3800 jitter transfer characteristics are shown below:
