Patent number: 11606095Abstract: Disclosed is a reference clock gating circuit for outputting a reliable reference clock according to an external clock. The circuit includes a detection circuit and a gating component. The detection circuit includes: a first counter counting according to triggers of the external clock and thereby generating a first clock number; a second counter counting according to triggers of an accurate slow clock and thereby generating a second clock number; and a decision circuit determining whether a ratio of the first clock number to the second clock number satisfies a predetermined condition after the second clock number reaches a predetermined number, and thereby generating a gating signal to control the gating component.
