What Are Dcm's?why They Are Used? |

Answer» Digital clock manager (DCM) is a fully digital CONTROL system that uses FEEDBACK to maintain clock signal characteristics with ahigh degree of precision despite normal VARIATIONS in operating temperature and voltage. That is clock output of DCM is stable over wide range of temperature and voltage , and also skew associated with DCM is minimal and all PHASES of input clock can be obtained . The output of DCM coming form GLOBAL buffer can handle more load.
