Abstract
An oscillator includes a package having a first side, a second side, a third side, and a fourth side, a resonator and an oscillation circuit disposed in the package, an output terminal arranged along the first side of the package, and outputting a clock signal generated by the oscillation circuit, and a control terminal arranged along the second side of the package, and supplied with a digital control signal adapted to update an operation state of the oscillation circuit.
Claims7
An oscillator comprising:
- a package having a first side, a second side, a third side, and a fourth side;
- a resonator and an oscillation circuit disposed in the package;
- an output terminal disposed outside the package and arranged along the first side of the package, and outputting a clock signal generated by the oscillation circuit;
- a control terminal disposed outside the package and arranged along the second side of the package, and supplied with a digital control signal adapted to update an operation state of the oscillation circuit;
- a first wiring pattern and a second wiring pattern disposed in the package, electrically connecting a pair of terminals of the resonator and the oscillation circuit to each other, and extending toward the third side of the package;
- a third wiring pattern disposed in the package, electrically connected to the output terminal, and having no crossing with the first and second wiring patterns in a planar view;
- a fourth wiring pattern disposed in the package, electrically connected to the control terminal, and having no crossing with the first through third wiring patterns in the planar view;
- and
- a fifth wiring pattern disposed between one of the first and second wiring patterns and one of the third and fourth wiring patterns in the package, and electrically connected to a power supply terminal supplied with one of a power supply potential and a reference potential.
