To provide an oscillator with clock information including a long-wave receiver for receiving a long-wave standard radio wave with high hour accuracy and time accuracy by obtaining clock data demodulated from a long-wave standard radio wave received by the long-wave receiver, and an oscillating signal phase-synchronized with a carrier frequency of the long-wave standard radio wave or a multiplication signal obtained by frequency-multiplying the carrier frequency as a frequency reference signal, thereby solving the problem of the conventional oscillator of the electric apparatus for generating a clock signal, wherein the oscillator does not have enough frequency accuracy, so that a clock difference is caused in the electric apparatus.

This synchronous oscillator with clock information is provided with a long-wave receiver for receiving and amplifying a long-wave standard radio wave, outputting a carrier signal, and demodulating and outputting a clock signal. The oscillator outputs an oscillation signal phase-synchronized with the carrier signal regenerated from the long-wave standard radio wave and the clock signal.
