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: 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: 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: 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: At least some aspects of the present disclosure provide for a method. In some examples, the method includes receiving, at a circuit, data via a differential input signal, detecting a rising edge in the data received via the differential input signal, and precharging a common mode voltage (Vcm) node of the differential input signal responsive to detecting the rising edge in the data received via the differential input signal, wherein the Vcm node is a floating node.

Abstract: Methods and systems of adaptive equalization to compensate channel loss are disclosed. A method includes detecting a peak amplitude of an equalizer output signal and selecting a set of reference voltage levels from M sets based on the peak amplitude of the equalizer output signal, each of the M sets having N reference voltage levels. The method includes continuing to increase an equalization level in predetermined steps to a next higher equalization level if the applied equalization level does not correspond to the over-equalization level and evaluating the distribution of the resulting hit counts for each increase to the next higher equalization level until the applied equalization level corresponds to the over-equalization level. The method includes decreasing to the previously applied lower equalization level if the applied equalization level corresponds to the over-equalization level.
