GENERAL DESCRIPTION

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. The AD9547 con-

tinuously generates a clean (low jitter), valid output clock, even

when all references fail, by means of digitally controlled loop and

holdover circuitry.

The AD9547 operates over an industrial temperature range of

−40°C to +85°C.
