PROBLEM TO BE SOLVED: To maintain an oscillation frequency with high accuracy despite a change of an impressed voltage accompanying a temperature change in a VC-TCXO10 generating a nominal oscillation frequency upon impressing a reference voltage to a control voltage input terminal 22.;SOLUTION: A constant voltage circuit 11 generates a constant voltage supplied to a crystal oscillation circuit 14. A constant voltage output terminal 20 is a terminal which derives the constant voltage to the outside. At the time of an adjustment of a temperature-oscillation frequency characteristic of a VC-TCXO10 in a thermostatic oven 30, a connection line 38 is connected between the constant voltage output terminal 20 and a control voltage input terminal 22, and control data of a temperature compensation circuit 12 is set from a temperature compensation circuit adjustment terminal 21 so that the oscillation frequency may become a nominal value over the whole operating allowable temperature range. At the time of mounting the VC-TCXO10 on a mobile wireless device 45, a connection line 52 is connected between the constant voltage output terminal 20 and the control voltage input terminal 22.;COPYRIGHT: (C)2009,JPO&INPIT
