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: An integrated circuit includes a combined serial data output and interrupt output terminal, a serial communication control circuit; an interrupt generation circuit, and an output circuit. The output circuit includes a serial data input, an interrupt input, and a combined serial data and interrupt output. The serial data input is coupled to a serial data output of the serial communication circuit. The interrupt input is coupled to an interrupt output of the interrupt generation circuit. The combined serial data and interrupt output is coupled to the combined serial data output and interrupt output terminal.

Abstract: In an example, a method of operating a repeater having an isolation barrier to isolate a host side of the repeater from a peripheral side of the repeater, the repeater operable to be coupled to a universal serial bus (USB), includes causing the host side to enter into a suspend mode. The method also includes, responsive to entering the suspend mode, disabling a host isolation transceiver at the host side. The method includes periodically enabling the host isolation transceiver to transmit a data signal from the host side to the peripheral side. The method includes exiting the suspend mode. The method also includes enabling the host isolation transceiver.

Abstract: A serial bus repeater includes first and second ports adapted to be coupled to respective devices. A first termination resistor network couples to the first port. A second termination resistor network couples to the second port. A squelch detect circuit couples to the first bus port and is configured to detect activity on the first bus and to generate a squelch signal responsive to detection of activity on the first port. A first state machine is configured to: determine an elapsed time during which the squelch signal indicates activity on the first port; determine that the elapsed time exceeds a first threshold; and, responsive to the determination that the elapsed time exceeds the first threshold, assert configuration signals to reconfigure the first and second termination resistor networks.

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.
