SYNC IN MULTI-CORE SYSTEMS
In a multi-core system each core
requires its own sync connection. The
router in each core in turn provides
sync over the network to the I/O
boxes connected to it.
It is vitally important that all cores on
the same network are locked to a sync
derived from and locked to the same
source. If any routers are clocked by free
running sync, or if they are derived from
different sources, both network audio and
communications will be compromised.
Cores running on different syncs can
cause instability leading to the loss of I/O
boxes and unreliable error messaging.
If sync is being distributed via equipment
such as regenerators / buffers, it is
important to ensure that they are all set to
lock to the correct input from the master
sync generator.
