TEMPERATURE COMPENSATED CRYSTAL OSCILLATOR

摘要

PROBLEM TO BE SOLVED: To provide a temperature compensated crystal oscillator, in which frequency stability is satisfactorily maintained. SOLUTION: In the temperature compensated crystal oscillator, in which an IC integrating an oscillation circuit at least is provided while having a power source and output and automatic frequency control voltage input terminals and the frequency temperature characteristics of the crystal oscillator are compensated, the power source and at least one of output and automatic frequency control voltage input terminals are provided with Q damp resistance for reducing the resonance sharpness of a resonance circuit caused by inductance generated when packaging on a circuit board and stray capacitance existent near the respective terminals of the IC.
