Abstract

Disclosed is a new clock splitter circuit whose split outputs, called C-clock and B-clock here, can be fully independently controlled. In recent big, high-density chips, separate control of C-clock and B-clock is, as well known, important in effectively saving power consumption and still making macros or circuit blocks ready for fast recovery and operation at an appropriate timing by stopping internal clocks and, at the same time, running macros' or blocks' input interface circuits' clock which is C-clock or B-clock depending on which clock is used in the input interface circuits. Fig.1 shows the disclosed new clock splitter circuit. Fig.1
