Description	Quad/Octal Input Network Clock Generator/Synchronizer
Datasheet	AD9548 Datasheet

The AD9548 provides synchronization for many systems, including synchronous optical networks (SONET/SDH).

The AD9548 generates an output clock synchronized to one of up to four differential or eight single-ended external input references.

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