AD9548 Datasheet (Analog Devices) - Quad/Octal Input Network Clock Generator/Synchronizer

AD9548, Quad/Octal Input Network Clock Generator/Synchronizer

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
