Claim of US Patent No. 10,483,983

1. A clock generating circuit, comprising:a dividing unit that divides a reference clock to generate a divided clock, the divided clock having a frequency of 1/N times of a frequency of the reference clock, where N is an integer of two or more; and
a distribution unit that distributes the reference clock to a first route and a second route, the first route including an output terminal that outputs a clock with a frequency identical to the frequency of the reference clock, the second route including the dividing unit,
wherein the dividing unit comprises:
one or more amplifiers;
one or more dividing circuits; and
a correction circuit, disposed between the amplifier and the dividing circuit, the correction circuit corrects a level of an input clock input to the dividing circuit.
