Product Details
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.
Applications
- Network synchronization
- Cleanup of reference clock jitter
- GPS 1 pulse per second synchronization
- SONET/SDH clocks up to OC-192, including FEC
- Stratum 2 holdover, jitter cleanup, and phase transient control
- Stratum 3E and Stratum 3 reference clocks
- Wireless base stations, controllers
- Cable infrastructure
- Data communications
