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.
