摘要： A clock signal generator for a USB device. The clock signal generator includes a control circuit and a clock generator that does not need to include a crystal oscillator. The control circuit counts the cycle of the clock signal during the period between two sync signals successively inputted, and generates a frequency control signal corresponding to the count value. The clock generator generates the clock signal with a frequency corresponding to the frequency control signal. The clock signal generator can generate a clock signal that is suitable for the data transfer rate defined, in the USB specification. In addition, the clock; signal generator can generate an RX clock signal so that an RX data signal can be recovered with its energy being stable.

摘要： A voltage-glitch detection circuit includes a voltage comparator having two input terminals with different capacitance resistance charge/discharge time. Voltage dividers are coupled to the two input terminals of the voltage comparator respectively, and commonly receive a supply voltage. One of the voltage dividers is supplied to the voltage comparator as a reference voltage of the voltage comparator, and the other is supplied as a glitch detection voltage to the voltage comparator.
