Wander Transfer â 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 SM3G, when configured for the appropriate stratum 3 bandwidth frequency, meets the stratum 3 requirements,
Jitter Generation â 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

Jitter Transfer â 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.
