Abstract:
1. A bridge device providing data transfer between a PCIE standard and a USB standard, comprising: a clock generator, comprising: a crystal oscillator, having a first terminal and a second terminal; an inverter coupled to the crystal oscillator in parallel, generating a first signal and a second signal at the first and second terminals of the crystal oscillator, respectively; a first circuit coupled to the first terminal of the crystal oscillator, generating a first clock signal with a constant frequency according to the first signal; and a second circuit coupled to the second terminal of the crystal oscillator, generating a second clock signal with a variable frequency according to the second signal; a PCIE module coupled to the clock generator; and a USB module coupled to the PCIE module, and performing data transfer complying with the USB standard according to the first clock signal and the second clock signal, wherein the crystal oscillator is directly connected to the first circuit by the first terminal, and the crystal oscillator is directly connected to the second circuit by the second terminal.
