Abstract:
The present invention discloses a USB3.0 clock frequency generation device without crystal oscillator, that is, the crystal oscillator used in the USB3.0 device (or apparatus) is removed and replaced with an oscillator circuit module in the present invention, in which a simple circuit module is added to the controller circuit of the USB3.0 device to provide accurate and proper timing signals needed. The oscillator circuit module includes an oscillator block, a frequency divider block, a delta-sigma modulator block, and a preset number block.
