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
continuously 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.
