Abstract: Two super-speed lanes may be enabled on a single USB cable. In an exemplary, non-limiting aspect, the USB cable is a Type-C cable. In further non-limiting aspects, the super-speed lanes may be present even if there is no USB 2.0 lane present on the D+/D− pins of the USB cable. Use of the second super-speed lane increases data throughput. Eliminating the requirement that the D+/D− pins be used for USB 2.0 data allows greater flexibility in the use of the USB connection because audio or video data may be sent over the D+/D− pins instead of USB 2.0 data. Further, the use of the two super-speed lanes allows a single computing element to operate as a host on one lane and a device on a second lane.

Abstract: Low latency transmission systems and methods for long distances in SOUNDWIRE systems are disclosed. In an exemplary aspect, a SOUNDWIRE sub-system is coupled to a long cable through a bridge. The bridge converts SOUNDWIRE signals to signals for transmission over the long cable and converts the signals from the long cable to the SOUNDWIRE signals for transmission in the SOUNDWIRE sub-system. Conversion between signal types may include concatenating signals of a similar type into a group that is serially transmitted over the long cable. Concatenation of bit slots in this manner consumes minimal overhead in bus turnaround, thereby reducing latency. In further aspects, the functionality of the bridge may be incorporated into a headset or a mobile terminal.

Abstract: Embedded Universal Serial Bus (USB) debug (EUD) for multi-interfaced debugging in electronic systems are disclosed. Electronic systems contain complex integrated circuits (ICs) that require extensive testing and debugging to ensure good quality and performance. In exemplary aspects, an EUD is provided in an electronic system. The EUD is configured to send control information to and/or collect debugging information from multiple internal debugging interfaces in the electronic system. The EUD is also configured to convert the debugging information into a USB format so that the debugging information can be externally accessed through a USB interface provided by the electronic system. The EUD can provide non-invasive monitoring of the electronic system. The electronic system is able to use a USB port for communications in a mission mode while EUD is enabled. Additionally, the electronic system can turn on or off all system clocks during power-saving mode while the EUD continues to function.

Abstract: Apparatuses and methods to distinguish proprietary, non-floating and floating chargers for regulating charging current are disclosed. In one aspect, a charger detection circuit is provided in a portable electronic device. The charger detection circuit is configured to detect whether a connected Universal Serial Bus (USB) charger is compliant with a USB battery charging specification. If the connected USB charger is non-compliant with the USB battery charging specification, the charger detection circuit is configured to further detect if the non-complaint USB charger is a non-compliant floating USB charger or a non-compliant proprietary USB charger. If the connected USB charger is determined to be a non-compliant proprietary USB charger, the portable electronic device can be configured to draw up to a maximum charging current according to the USB battery charging specification.

Abstract: A method for offset calibration of a voltage comparator is disclosed according to certain aspects of the present disclosure. The method includes applying a first bias voltage to a gate of a first compensation transistor, wherein the first compensation transistor is coupled in series with a first input transistor of the voltage comparator. The method also includes applying a second bias voltage to a gate of a second compensation transistor, wherein the second compensation transistor is coupled in series with a second input transistor of the voltage comparator. The method further includes sensing a logic value at an output of the voltage comparator, and adjusting the first bias voltage and the second bias voltage based on the sensed logic value.

Abstract: In certain aspects, a regulator includes a variable-impedance switch coupled between a supply rail and a circuit block, wherein the variable-impedance switch has an adjustable impedance. The regulator also includes a voltage level comparator configured to compare a block voltage at the circuit block with a reference voltage, and to output a first signal indicating whether the block voltage is higher or lower than the reference voltage based on the comparison. The regulator also includes a slope detector configured to determine whether the block voltage is rising or falling, and to output a second signal indicating whether the block voltage is rising or falling based on the determination. The regulator further includes a controller configured to receive the first signal and the second signal, and to control the impedance of the variable-impedance switch based on the first signal and the second signal.

Abstract: A link layer to physical layer (PHY) serial interface is disclosed. In one aspect, a system on a chip (SoC) integrated circuit (IC) includes a link layer circuit, and a remote IC includes a Universal Serial Bus (USB) PHY circuit. A bus having four or fewer wires connects the two ICs. A link bridge communicates with the link layer circuit and serializes USB Transceiver Macrocell Interface (UTMI) signaling received from the link layer circuit as high speed (HS) USB messages for transmission to the remote IC. The link bridge also receives HS messages from the USB PHY circuit on the remote IC. The link bridge deserializes the HS messages to extract UTMI signaling and passes the extracted UTMI signaling to the link layer circuit.

Abstract: A series of current repeaters with localized feedback is provided. Each current that precedes a subsequent current repeater in the series is configured to receive a feedback current from the subsequent current repeater and generate an error signal accordingly with a differential amplifier so as to reduce current repetition errors that would otherwise result from an offset voltage in the differential amplifier.
