OSCILLATOR, ELECTRONIC APPARATUS, AND MOVING OBJECT

摘要

A oscillator includes a substrate having a first surface and a second surface, a first wiring layer and a second wiring layer disposed respectively on the first and second surfaces, and a plurality of through holes electrically connecting the first and second wiring layers to each other, a resonator disposed above the first surface of the substrate, and having a resonator element, a pair of electrodes sandwiching the resonator element, and a pair of terminals adapted to electrically connect the pair of electrodes to the first electrode layer, and at least one semiconductor device disposed on the second surface of the substrate, adapted to generate an oscillation signal, and having first and second terminals electrically connected respectively to the pair of terminals of the resonator via the second wiring layer and the first wiring layer, and a third terminal supplied with a digital control signal, wherein a distance between each of the first and second terminals and the pair of terminals of the resonator is shorter than a distance between the third terminal and the pair of terminals of the resonator.
