Abstract: An integrated circuit is provided. The integrated circuit includes a communication-mode determination circuitry configured to detect a signal level at one or both of a first data line and a second data line and to determine whether a communication mode of the first data line and the second data line is a first universal series bus (USB) communication mode or a second USB communication mode. The integrated circuit also includes a first transceiver circuitry configured to operate in one of multiple modes, based on the communication mode determined. The integrated circuit also includes a second transceiver circuitry configured to operate in one of multiple modes, based on the communication mode determined. A maximum signal level of the first USB communication mode is greater than a maximum signal level of the second USB communication mode.

Abstract: An integrated circuit is provided. The integrated circuit includes a mapping circuit configured to determine a state associated with a first universal series bus (USB) communication mode based on one or both of a signal level on a first data line and a signal level on a second data line. The integrated circuit also includes a line state converter circuit configured to generate a line state associated with a second USB communication mode based on the determined state and based on one or both of the signal level on the first data line and the signal level on the second data line.
