    Abstract: Aspects of the present disclosure provide for a system. In at least some examples, the system includes an embedded Universal Serial Bus 2 (eUSB2) device having a first receiver and a first transmitter, a processor, a second transmitter coupled to the processor, a second receiver coupled to the processor, a drive low circuit coupled to the processor second transmitter, and differential signal lines having a length greater than ten inches. The differential signal lines are coupled at a first end to the first receiver and the first transmitter and at a second end to the second transmitter and the second receiver. The processor is configured to control the drive low circuit to drive the differential signal lines low with a logic ‘0’ to cause the first receiver to receive the logic ‘0’ and a value of a signal present on the differential signal lines to reach about 0 volts.

    Abstract: A redriver system adapted for coupling to a first device and to a second device includes first and second transmitter drivers and a snoop circuit. The first transmitter driver has a first enable input. The second transmitter driver has a second enable input. The snoop circuit is coupled to the first and second enable inputs. The snoop circuit is configured to determine whether the first device and the second device are to operate according to a first protocol. Responsive to the snoop circuit determining that the first and second devices are to operate according to the first protocol, the snoop circuit enables the first transmitter driver and disables the second transmitter driver. Responsive to the snoop circuit determining that the first and second devices are not to operate according to the first protocol, the snoop circuit disables the first transmitter driver and enables the second transmitter driver.

    IPC: G06F13/42

    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.
