  • Patent number: 10256801
    Abstract: An integrated circuit with clock detection and selection function for use in a storage device includes: an embedded oscillator, a detection circuit and a selection circuit. The embedded oscillator is configured to generate an embedded clock signal. The detection circuit includes a sampling and counting circuit and a clock determination circuit. The detection circuit, and is configured to detect existence of a reference clock signal provided by a host based on sampling and counting operations that are performed according to a signal on a clock signal lane and the embedded clock signal. The selection circuit is coupled to the detection circuit and the embedded oscillator, and is configured to select one of the embedded clock signal and the signal on the clock signal lane according to the existence of the reference clock signal as an output clock signal, thereby to provide the output clock signal to the storage device.
