Classification: CPC H | IPC H

Claim 18:
19. An electronic system comprising:
an oscillator configured to generate an oscillation signal having a natural frequency by injecting a first injection signal and a second injection signal through a first phase, a second phase, a third phase and a fourth phase;
an integrated circuit (IC) chip configured to convert the oscillation signal into at least one clock signal; and
at least one external device configured to receive one of the at least one clock signal,
wherein the oscillator includes
a crystal oscillation circuit configured to generate the oscillation signal,
an injection circuit configured to inject the first injection signal and the second injection signal into the crystal oscillation circuit in each of the first and fourth phases,
a dithering circuit configured to transmit a first control signal for generating the first injection signal to the injection circuit in the first phase and the second phase, and
a phased-lock loop (PLL) circuit configured to lock a phase of the first injection signal to the natural frequency in the third phase, to transmit a second control signal for generating the second injection signal to the injection circuit.
