Title:
CRYSTAL OSCILLATOR
Document Type and Number:
Japanese Patent JP2017200032
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To stably output two oscillation signals simultaneously.SOLUTION: A crystal oscillator 1 comprises: a crystal resonator 2; a first oscillation circuit 3 for oscillating the crystal resonator 2 with a fundamental wave to generate a first oscillation signal of a first frequency; and a second oscillation circuit 4 for overtone-oscillating the crystal resonator 2 to generate a second oscillation signal of a second frequency higher than the first frequency. The second oscillation circuit 4 includes: a plurality of second capacitors 45, 46 provided between the crystal resonator 2 and the ground; and an inductor 49 connected in parallel to at least one second capacitor among the plurality of second capacitors 45, 46.SELECTED DRAWING: Figure 1
