Abstract: In some examples, an apparatus includes a circuit configured to receive communication on a first bus. The circuit is also configured to provide the communication on a second bus for a first period of time. The circuit is also configured to monitor a duration of the providing of the communication on the second bus. The circuit is also configured to, responsive to the duration exceeding a threshold amount, stop providing the communication on the second bus for a second period of time.

Abstract: Data communication devices, e.g., eUSB2 repeaters, include a partial bit filter to filter out a partial bit so it is not transmitted. The partial bit filter includes state-detection-and-hold circuitry having first and second differential signal inputs, a first output and a second output; logic circuitry having a first input coupled to the first output of the state-detection-and hold circuitry, and a second input coupled to the second output of the state-detection-and hold circuitry; and filter circuitry coupled to the logic circuitry and having a control output. The filter circuitry may be implemented as a latch or a network of flip flops. The output control signal of the partial bit filter may be applied to a transmitter in an eUSB2 repeater or to a pass-gate at the output of the transmitter.
