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. Using a digitally controlled loop and holdover circuitry， the AD9549 continues to generate a clean （low jitter）， valid output clock during a loss of reference condition， even when both references have failed. The AD9549 operates over an industrial temperature range of −40°C to +85°C.
