Abstract: A structure of an integrated crystal oscillator package has a first quartz crystal resonator, a second quartz crystal resonator, and application-specific integrated circuit chip (ASIC) combined in a package. The ASIC has a switch control for receiving audio formats of 44.1 kHz and 48 kHz with different hi-fidelity (hi-fi). The first quartz crystal resonator has a first clock rate corresponding to the 44.1 kHz frequency and the second quartz crystal resonator has a second clock rate corresponding to the 48 kHz frequency to be switched by the present invention in operation.

Abstract: A complex optical proximity sensor includes a substrate, a light emitter coupled to the substrate, an application-specific integrated circuit chip coupled to the substrate and embedded in a proximity sensor, a barrier disposed between the application-specific integrated circuit chip and the light emitter, and an ambient light detection chip manufactured in advance and then coupled to the application-specific integrated circuit chip thereon with a pre-determined height. The elements are disposed within a limited area of an aperture and, with a manufacturing method of the complex optical proximity sensor, the detection angle of the ambient light is thereby maximized and the detection angle of the proximity sensor is thereby minimized.

Abstract: A complex optical proximity sensor has a vertical-cavity surface emitting laser (VCSEL), an ambient lights detection chip, and a proximity sensor (PS) arranged in linear alignment to form a self-integrated barrier within the structure. The PS only receives lights with a first wavelength and a first energy and the ambient lights detection chip solely receives lights with a second wavelength and a second energy to prevent the VCSEL from interfering with the PS. Meanwhile, the arrangement has the ambient lights detection chip disposed in a middle section of an oblong opening to maximize a detection angle of ambient lights.
