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: In described examples, an integrated circuit includes an on-off keying (OOK) digital isolator, which includes a first circuitry, a multiplexer, an OOK modulator, an isolation barrier, an OOK envelope detector, and a second circuitry. The first circuitry generates and outputs a calibration signal. The multiplexer has a data signal input, and an input coupled to a first circuitry output. An OOK modulator input is coupled to a multiplexer output. An isolation barrier input is coupled to an OOK modulator output. An OOK envelope detector input is coupled to an isolation barrier output. The second circuitry includes an input coupled to an OOK envelope detector output, and an output coupled to an OOK envelope detector control input. The second circuitry detects a duty cycle distortion (DCD) of the OOK envelope detector output, and outputs a control signal to change the OOK envelope detector output's duty cycle based on the detected DCD.

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: An isolating repeater and corresponding method for Universal Serial Bus (USB) communications. The isolating repeater includes, on either side of a galvanic isolation barrier, front end circuitry coupled to a pair of external terminals, a full speed (FS) transceiver adapted to drive and receive signals over one or more FS isolation channels, and a high speed (HS) transceiver adapted to drive signals over a one HS isolation channel and receive signals over another HS isolation channel. The front end circuitry encodes received signals corresponding to HS data into two-state signals for transmission over one HS isolation channel, and encodes received signals corresponding to HS signaling into two-state signals for transmission over one or more of the FS isolation channels. The front end circuitry on the other side of the isolation barrier decodes the two-state signals received over the one or more FS isolation channels and the two-state signals received over the HS isolation channel for transmission at its external terminals.
