GENERAL DESCRIPTION
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.
