Abstract
A clock formation circuit to form from a digital data signal a formation clock signal corresponding to a data clock controlling an inversion timing of the digital data signal having a circuitry which provides an information signal of the phase difference between the digital data signal and the formation clock signal and circuitry which outputs the formation clock signal having a frequency controlled based at least on an integrated information signal obtained by limiting a current flowing through a capacitor having a terminal voltage there across varying in accordance with the phase difference information signal.
