Abstract
An oven-controlled crystal oscillator according to one or more embodiments includes a core section having at least an oscillation IC, a crystal resonator, and a heater IC. The core section is hermetically encapsulated in a heat-insulating package. The core section is supported by the package via a core substrate. The core substrate is connected to the package outside a region where the core section is provided in plan view.
Claims8
An oven-controlled crystal oscillator comprising a core section including at least an oscillation IC, a piezoelectric resonator, and a heater IC, the core section being hermetically encapsulated in a heat-insulating package, wherein
- the core section has a layered structure in which the piezoelectric resonator and the heater IC are laminated, and an area of the heater IC is greater than an area of the piezoelectric resonator,
- the core section is supported by the heat-insulating package via a core substrate, and
- the core substrate is connected to the heat-insulating package outside a region where the core section is provided in plan view.
