Synchronization
The SYNC control input is used to synchronize all
divider outputs of the post divider. When a HIGH-LOW
transition is applied to the SYNC control input the
outputs are disabled when all post-divider outputs are
LOW, see “Output Synchronization Controlled by
January 2008
Output Synchronization Controlled by SYNC Timing Diagram
17
SYNC Timing Diagram” for details. Once SYNC is
asserted with a rising edge, the outputs are enabled
when all internal divider stages are reaching their
LOW state. This ensures a simultaneous switching of
all outputs with the next LOW-HIGH transition of the
pre-divider clock.
