A sync operation brings all outputs that have not been excluded
(by the nosync bit) to a preset condition before allowing the
outputs to begin clocking in synchronicity. The preset condition
takes into account the settings in each of the channel’s start high
bit and its phase offset. These settings govern both the static
state of each output when the SYNC operation is happening and
the state and relative phase of the outputs when they begin
clocking again upon completion of the SYNC operation.
Between outputs and after synchronization, this allows for the
setting of phase offsets.
The AD9516 outputs are in pairs, sharing a channel divider per
pair (two pairs of pairs, four outputs, in the case of CMOS). The
synchronization conditions apply to both outputs of a pair.

Each channel (a divider and its outputs) can be excluded from
any sync operation by setting the nosync bit of the channel.
Channels that are set to ignore SYNC (excluded channels) do
not set their outputs static during a sync operation, and their
outputs are not synchronized with those of the nonexcluded
channels.
Clock Outputs
The AD9516 offers three different output level choices:
LVPECL, LVDS, and CMOS. OUT0 to OUT5 are LVPECL
differential outputs; and OUT6 to OUT9 are LVDS/CMOS
outputs. These outputs can be configured as either LVDS
differential or as pairs of single-ended CMOS outputs.
