Abstract
An oscillating device includes a first quartz crystal resonator, a driving circuit, a first buffer, an attenuator, a second quartz crystal resonator, and a second buffer. The first quartz crystal resonator and the second quartz crystal resonator respectively have a first resonant frequency and a second resonant frequency. The driving circuit drives the first quartz crystal resonator to generate a first oscillating signal having the first resonant frequency. The first buffer generates a first clock signal in response to the first oscillating signal. The attenuator reduces the wave swing of the first clock signal to generate an attenuated signal. The second quartz crystal resonator rectifies the attenuated signal to generate a second oscillating signal having the second resonant frequency. The second buffer generates a second clock signal in response to the second oscillating signal.
