Abstract
An apparatus includes a first circuit, a second circuit and a third circuit. The first circuit may be configured to generate a first code by counting a number of cycles of an input clock signal in a period determined by (i) an output clock signal and (ii) a second code. The second code may be variable. The second circuit may be configured to generate a third code by a delta-sigma modulation of the first code. The third circuit may be configured to generate the output clock signal (i) in response to the third code and (ii) within an accuracy determined the second code.
