Cable Simulator
Simulated Cable Response
A selectable cable simulator inserts the response
of a long, typical digital audio cable in the front-
panel Digital Out signal.

Main Output Residual Jitter
Clock Source From Audio
Frequency Offset = 0
Frequency Offset < > 0 or Clock
Source is Variable
Clock Source From Ref
0.05 UI p-p maximum
0.08 UI p-p maximum
(0.08 UI p-p + reference jitter) maximum
Reference signal jitter up to 15 kHz adds directly
to output jitter. Reference input jitter above
15 kHz is attenuated by 6 dB per octave.
Reference Output Variable Parameters
Clock Rate Range The reference output can be driven from the
same clock that drives the main output, in which
case the specifications of the main clock apply.
Alternately, the reference output can be timed
from the internal 48 kHz clock, or from the clock
applied to the Digital Reference In connector.
