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 signal conditioner can include a state machine configured to detect a predetermined protocol level mode of a data signal on a bi-directional serial bus. The signal conditioner can also include a re-driver configured to inject current into at least one of a rising edge and a falling edge of the data signal on the bi-directional serial bus in response to the detection of the predetermined protocol level mode.
