Specifications subject to change without notice

Phase Transients – A phase transient is an unusual step or change in the phase-time of a signal over a relatively short time

period. This may be due to switching between equipment, reference switching, diagnostics, entry or exit to/from Hold Over, or input

reference transients. The SM34 performance for reference switches is shown below:

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 SM34, 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.

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 SM34 jitter transfer characteristics are shown below:
