Abstract
A clock frequency supply device includes: a frequency tuner configured to receive an input signal with a carrier frequency, and tune an oscillation frequency of an oscillator based on the carrier frequency; an injector configured to inject the input signal directly into the oscillator after the tuning of the oscillation frequency is completed; and an oscillator configured to generate a reference clock signal with a reference clock frequency based on the injected input signal.
Claims27
A clock frequency supply device, comprising:
- an oscillator;
- a frequency tuner configured to receive an input signal with a carrier frequency, and tune an oscillation frequency of the oscillator based on the carrier frequency;
- and
- an injector configured to inject the input signal directly into the oscillator after the tuning of the oscillation frequency is completed,
- wherein the oscillator is configured to generate a reference clock signal with a reference clock frequency based on the injected input signal,
- wherein the injector comprises:
- a mode switch configured to control feeding of a feed signal generated from the input signal with respect to the oscillator;
- and
- an injection controller configured to restrict an enablement of the feed signal before the tuning of the oscillation frequency is completed, and to allow the enablement of the feed signal after the tuning of the oscillation frequency is completed.
