    Abstract: At least some aspects of the present disclosure provide for a method. In some examples, the method includes receiving 2-line data in an embedded Universal Serial Bus (eUSB) format. The method further includes encoding the 2-line data into a single signal. The single signal comprises a first symbol corresponding to a first state change of the 2-line data and a second symbol corresponding to a second state change of the 2-line data.

    Abstract: A serial bus signal conditioner circuit includes receiver circuitry, a mode identification circuit, and an edge-rate booster circuit. The receiver circuitry is configured to receive signals transmitted on a serial bus. The mode identification circuit is coupled to the receiver circuitry, and is configured to identify initiation of or return to high-speed signaling on the serial bus based on sequences of the signals transmitted on the serial bus. The edge-rate booster circuit is coupled to the mode identification circuit, and is configured to identify edges of a differential signal transmitted on the serial bus, and to supply a differential current to the serial bus based on identification of an edge of the differential signal.

    Abstract: A method includes determining a charging port mode by receiving a data contact detect (DCD) Complete signal, reducing a voltage on a first data pin of a Universal Serial Bus (USB) connector of a portable device, and determining that a condition is true when a voltage on a second data pin of the USB connector is equal to or greater than 0.8 to 2.0 Volts (V), and is false otherwise. When the condition is true, a first signal is sent on a control circuit output indicating indicate that the PD is connected to a dedicated charging port (DCP) of Divider 0 mode. When the condition is false, a second signal is sent on the control circuit output indicating that the PD is connected to a DCP of 1.2V short mode.

    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.

    IPC: H04L25/03

    Abstract: A system for selecting an equalizer setting of an equalizer to equalize signals received via a communications link. Starting with a first (e.g., minimum) equalizer setting and a threshold voltage near the mid-eye voltage of the equalized output signal, the system estimates the amplitude of the inner eye of the equalized output signal by comparing the equalized output signal to a series of threshold voltages. If the amplitude of the equalized output signal is less than ideal, the system dynamically increases the equalizer setting. The system quickly converges on the equalizer setting for the communication link because, rather than comparing the output signal at every voltage offset using every equalizer setting, the system only evaluates the equalizer settings necessary to select the equalizer setting for the communications link and uses only the voltage offsets necessary to evaluate each equalizer setting.

    Abstract: An apparatus includes a multiport hub, a single bridge configured to communicatively couple together a plurality of hosts and to emulate a slave device to each such host, and a plurality of connection port. The apparatus further includes a configurable data path network coupled to the multiport hub, the single bridge, and the plurality of connection ports. The configurable data path network is configured to selectively provide for a connection port for which a host is detected, data communications through the single bridge between the multiport hub and the connection port, and for a connection port for which no host is detected, data communications between the multiport hub and the connection port that bypass the single bridge. Corresponding methods are also so disclosed.
