Abstract: This disclosure generally relates to USB TYPE-C, and, in particular, DISPLAYPORT Alternate Mode communication in a USB TYPE-C environment. In one embodiment, a device determines a DISPLAYPORT mode and determines an orientation of a USB TYPE-C connector plug. A multiplexer multiplexes a DISPLAYPORT transmission based in part on the determined orientation of the USB TYPE-C connector plug.

Abstract: Two CAN bus transceivers utilized in a single integrated circuit package with the CAN bus connections between the two transceivers being inverted. Thus, one transceiver is connected to the CAN bus high and low lines while the other transceiver is connected to the CAN bus low and high lines. Both transceivers power up in a standby condition and each transceiver is monitoring for wake up signals on the CAN bus. The transceiver that is correctly connected to the CAN bus detects wake up signals. When the wake up signals are detected at that transceiver, that transceiver is brought to full operating state and the other transceiver is placed in a full standby condition. Additional input resistance is provided with each transceiver to maintain the proper input resistance for the integrated circuit.
