Description	Dual/Quad Input Network Clock Generator/Synchronizer
Datasheet	AD9547 Datasheet

The AD9547 provides synchronization for many systems, including synchronous optical networks (SONET/SDH).

The AD9547 generates an output clock that is synchronized to one of two differential or four single-ended external input references.

The digital PLL allows for reduction of input time jitter or phase noise associated with the external references.
