ABSTRACT:
A temperature-compensated crystal oscillator is provided with an IC (integrated circuit) having a power supply terminal, an output terminal, and an automatic frequency control (AFC) voltage input terminal. In the temperature-compensated crystal oscillator, at least one oscillation circuit is integrated and the frequency-temperature characteristic of a quartz crystal unit is compensated. The temperature-compensated crystal oscillator includes one or more damping resistors for reducing the resonance acuteness of parasitic resonance circuits which result from inductance produced when mounting the IC on a wiring board and stray capacitance existing in the vicinity of each terminal of the IC. The dumping resistors are connected to at least one of the power supply terminal, output terminal, and automatic frequency control voltage input terminal.
