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: A system includes a downstream facing port (DFP) coupled to a video source, an upstream facing port (UFP) coupled to a video sink, and a cable. The cable includes a first end that is connected to the DFP and a second end that is connected to the UFP. The cable is configured to carry a differential auxiliary transmission signal and detect polarity in the differential auxiliary transmission signal.

Abstract: A CAN bus transceiver includes CAN bus fault detection circuitry that can provide detailed information to simplify the task of the service technician when there is a CAN bus fault. Voltage and current measurements of the CAN bus are made and from them a fault type is determined. A time-domain reflectometer monitors the CAN bus signals for transmitted and reflected signals and from them a distance to the fault is determined. Either or both values are provided to a service technician to allow error determination and correction.

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.
