Product Detailed Description for AD9549
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.
Applications
- Network synchronization
- Reference clock jitter cleanup
- SONET/SDH clocks up to OC-192, including FEC
- Stratum 3/3E reference clocks
- Wireless base stations, controllers
- Cable infrastructure
- Data communications
