Abstract
The crystal oscillator device for simultaneously generating oscillator signals with a plurality of oscillation modes of a crystal unit, comprising: a primary resonator unit filtering the oscillator signal with a primary oscillation mode, which is one of the oscillation modes, from the output of the crystal unit, a secondary resonator unit filtering the oscillation signal, bearing a different resonance frequency from that of the primary resonator unit, with the primary oscillation mode from the output of the crystal unit, a primary phase synthesis unit, synthesizing the phases of the output signal of the primary resonator unit and the output signal of the secondary resonator unit, a tertiary resonator unit, a quaternary resonator unit, and a secondary phase synthesis unit.
