Abstract
PURPOSE: To get rid of an error due to the secular change, by detecting the phase shift of other clock through basing on one output of a generator which generates a number of clocks, and controlling the generator.
CONSTITUTION: A clock which has been taken out from the logical blocks 104, 105 is transmitted to the phase difference detection circuit 113, 114, and the phase is compared with that of a reference clock from the logical block 106. The output of the phase difference detection circuits 113, 114 is input to the control input of the delay control circuits 102, 103, and a phase error of the clock from the logical blocks 104, 105 is corrected by controlling the phase of the outputs 152, 153 from the clock generating circuit 101.
