GENERAL DESCRIPTION
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. The AD9548
continuously generates a clean (low jitter), valid output clock
even when all references have failed by means of a digitally
controlled loop and holdover circuitry.
The AD9548 operates over an industrial temperature range of
40°C to +85°C.
