Abstract: The USB chipset including a data processing unit, a transmitting unit, a first pin set and a second pin set is provided. The data processing unit generates a plurality of transmission information according to first information provided by a first device. The transmitting unit processes the transmission information to generate an output signal. The first pin set is configured to transmit the output signal to a second device. The second pin set is configured to transmit the output signal to the second device. When the first pin set transmits the output signal to the second device, the second pin set does not transmit the output signal to the second device. When the second pin set transmits the output signal to the second device, the first pin set does not transmit the output signal to the second device.

Abstract: A transmission circuit including an equalizer circuit, a slicer circuit, a signal detection circuit, and a control circuit is provided. The equalizer circuit performs an equalizing operation on an input signal according to preset states to output an equalizing signal corresponding to each preset state. The slicer circuit performs a slicing operation on the equalizing signal to output a slicing signal. The signal detection circuit detects and compares the equalizing signal and the slicing signal and accordingly adjusts the equalizer circuit to one of the preset states. The control circuit receives the slicing signal corresponding to each preset state, compares the slicing signal corresponding to each preset state with a plurality of signal patterns to generate a comparison result, and selects one of the preset states according to the comparison result, such that the control circuit let the equalizer circuit perform the equalizing operation according to the selected preset state.
