The device supports a set of main output clocks,
T
clocks, 'Frame-Sync' and 'Multi-Frame-Sync'. The
two main output clocks, T
independent of each other and are individually
selectable. The two secondary output clocks,
'Frame-Sync' and 'Multi-Frame-Sync', are derived
from T
are selectable from a range of pre-defined spot
frequencies and a variety of output technologies
are supported, as defined in Table 8.
