Oscillators

<p>The ZL30143 System Synchronizer and SETS device is a highly integrated device that provides all of the<br /> functionality that is required for a central timing card in carrier grade network equipment. The basic functions of a<br /> central timing card include:<br /> • Input reference monitoring for both frequency accuracy and phase irregularities<br /> • Automatic input reference selection<br /> • Support of both external timing and line timing modes<br /> • Hitless reference switching<br /> • Wander and jitter filtering<br /> • Master/slave crossover for minimizing phase alignment between redundant timing cards<br /> • Independent derived output timing path for support of the SETS functionality</p> <p><a href="https://www.microsemi.com/product-directory/sdh-sonet/4650-zl30143#resources" target="_blank">Click here for secure documentation</a></p>
