ADAT inputs may operate in an arbitrary phase relationship to the device Word
Clock. In addition, each device may have a different phase offset.
In order to ensure that groups A and B are played back correctly in-phase, the
start of every receivedADAT signal must be offset by no more than of a
Word Clock period with respect to the reference clock (internal or sync
source). If the phase difference is larger than this, the signal will nevertheless
still be correctly received, but may be shifted by one sample.
+/- 25%
For proper operation of SonicCore boards we
therefore took care, that all ADAT outputs are
correctly phased anytime- even those of multicard
systems!
Whenever a signal is present on the ADAT A or Z-Link A interface, the
will synchronize itself to this signal, regardIess of whether a signal is also
present on interface B. When a signal is present on interface B and no signal is
detected on interfaceA, the will synchronize itself to the interface

If only one Z-Link interface is connected, the other half of the converter
remains in ADAT mode. Since the converter always derives its sync clock from
the Z-Link data stream when in Z-Link mode, any device which is connected to
theADAT interface must be operated as a sync slave.
The Z-Link connectors must be driven by phase-aligned signals.

In a DAW-system composed of multiple S/TDM-
interconnected Scope boards inside a single
computer, the correct phase alignment of the Z-
Link signals is managed automatically.
If the two Z-Link streams are not properly phase-aligned, the mutes
itself completely.
