Title:
QUARTZ OSCILLATOR AND METHOD FOR MANUFACTURING QUARTZ OSCILLATOR
Document Type and Number:
WIPO Patent Application WO/2015/133472
Kind Code:
A1
Abstract:
A quartz oscillator (1) is provided with: a first oscillation circuit (13) which oscillates a quartz resonator (12) at a first frequency; a first impedance adjustment circuit (17) which adjusts the impedance of a first oscillation system having the quartz resonator (12) and the first oscillation circuit (13); a second oscillation circuit (14) which oscillates the quartz resonator (12) at a second frequency different from the first frequency; a second impedance adjustment circuit (18) which adjusts the impedance of a second oscillation system having the quartz resonator (12) and the second oscillation circuit (14); and a control circuit (19) which controls the first impedance adjustment circuit (17) and the second impedance adjustment circuit (18).
