24. SteadyClock

The SteadyClock technology of the Fireface 800 guarantees an excellent performance in all

clock modes. Thanks to a highly efficient jitter suppression, the AD- and DA-conversion always

operates on highest sonic level, being completely independent from the quality of the incoming

clock signal.

SteadyClock has been originally de-

veloped to gain a stable and clean

clock from the heavily jittery MADI

data signal (the embedded MADI

clock suffers from about 80 ns jitter).

Using the ADI-2's input signals

SPDIF and ADAT, you'll most proba-

bly never experience such high jitter

values. But SteadyClock is not only

ready for them, it would handle them

just on the fly.

Common jitter values in real world

applications are below 10 ns, while a

very good clock will have less than 2

ns.

The screnshot shows an extremely jittery SPDIF signal of about 50 ns jitter (top graph, yellow).

SteadyClock turns this signal into a clock with less than 2 ns jitter (lower graph, blue). The sig-

nal processed by SteadyClock is of course not only used internally, but also used to clock the

digital outputs. Therefore the refreshed and jitter-cleaned signal can be used as reference clock

without hesitation.
