描述 Description

The ZL30142 SONET/SDH/GbE Stratum 3 System Synchronizer and SETS device is a highly integrated devicethat provides all of the functionality that is required for a central timing card in carrier grade network equipment. Thebasic functions of a central timing card include:
? Input reference monitoring for both frequency accuracy and phase irregularities
? Automatic input reference selection
? Support of both external timing and line timing modes
? Hitless reference switching
? Wander and jitter filtering
? Master/slave crossover for minimizing phase alignment between redundant timing cards
? Independent derived output timing path for support of the SETS functionalityClick here for secure documentation
