AD9549 Datasheet (Analog Devices) - Dual Input Network Clock Generator/Synchronizer

AD9549, Dual Input Network Clock Generator/Synchronizer

The AD9549 provides synchronization for many systems, including synchronous optical networks (SONET/SDH).

The AD9549 generates an output clock, synchronized to one of two external input references.

The external references may contain significant time jitter, also specified as phase noise.
