Abstract: In an example, a data communication device includes one or more receivers, and one or more transmitters. The data communication device detects a start of frame packet (μSOF) on a data bus, wherein the μSOF indicates the start of a microframe; determines whether there are any data packets contained in the microframe during a first threshold period after the μSOF; and detects that there is no data packet contained in the microframe during the first threshold period after the μSOF, and in response, transitions at least one of the one or more transmitters from an active state to an OFF state, and transitions the at least one of the one or more transmitters from the OFF state to the active state prior to a switchback period before the end of the microframe.

Abstract: A method includes detecting a micro start of frame packet (μSOF) on a data bus. If there is at least one data packet contained in a microframe during the first threshold period after the μSOF, transmitters are held in an active state. If there is no data packet in the first threshold period after the μSOF, the transmitters are transitioned from the active state to an OFF state. The method also includes transitioning the transmitters from the OFF state to the active state prior to a switchback period before the end of the microframe. The method also includes transitioning the transmitters from the OFF state to the active state if a data packet is received in the OFF state. The method also includes dropping the data packet received in the OFF state and transitioning from the OFF state to the active state when the data packet is dropped.

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 circuit includes signal conditioner circuitry, level shifter circuitry, and state detector and controller circuitry coupled between the signal conditioner circuitry and the level shifter circuitry. The state detector and controller circuitry includes receiver circuitry and a finite state machine coupled to the receiver circuitry. The finite state machine is configured to detect a first data rate from signals, control operation of the signal conditioner circuitry responsive to detecting the first data rate, and control operation of the level shifter circuitry during a second data rate.

Abstract: Aspects of the disclosure provide for a method. In at least some examples, the method includes receiving, at a circuit, data via a differential input signal. The method further includes detecting a falling edge in the data received via the differential input signal. The method further includes holding an output of the circuit at a final logical value of the data. The method further includes disabling a transmitter of the circuit while holding the output of the circuit at the final logical value of the data. The method further includes releasing the output of the circuit from the final logical value of the data.

Abstract: High-speed data communication devices, e.g., repeaters, interfacing between a host and a peripheral operate such that high-speed components except for a host-side squelch detector are set or maintained in a deactivated state during an idle period of a micro frame. In an example, a start of a micro frame is detected on a data bus during a first time period. In a second time period after the first time period, the high-speed communication device determines whether at least one data packet is contained in the micro frame. When it is determined during the second time period that no data packet is contained in the micro frame, active components, except a squelch detector, are controlled to be inactive during a third time period after the second time period.

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: An embedded USB2 (eUSB2) repeater includes an eUSB2 port having first and second terminals. The eUSB2 port facilitates two-way communication between the repeater and an application processor unit (APU) according to voltage level specifications for eUSB2. The repeater includes a USB port having first and second terminals. The USB port facilitates two-way communication between the repeater and a Universal Asynchronous Receiver Transmitter (UART) according to voltage level specifications for US. The repeater includes a multiplexer having an input coupled to receive a control signal. The multiplexer selectively establishes connections between the first and second terminals of the eUSB2 port and the first and second terminals of the USB port.
