Abstract: A 10BASE-T1S PHY method and apparatus are provided for receiving an analog MDI signal conveying DME-encoded data at a receiver comparator to generate a digital output signal, processing the digital output signal using a pulse encoder to generate a pulse-coded output signal with pulses generated at each rising or falling transition in the digital output signal, processing the pulse-coded output signal with an output driver to generate a pulse-coded driver output signal that is transmitted to a receiver interface pin RX, processing the pulse-coded driver output signal with an input comparator to generate a pulse-coded comparator output signal, processing the pulse-coded comparator output signal using a pulse decoder to generate a DME-encoded PMA input signal in which timing asymmetries caused by processing at the receiver comparator and/or output driver have been eliminated, and then processing DME-encoded PMA input signal at a digital PHY circuit in the Ethernet PHY.

Abstract: A Controller Area Network (CAN) transceiver includes a receiver configured to determine a voltage differential signal from analog signalling received from a CAN bus and configured to provide a digital output signal at a receiver output to a CAN controller based on the voltage differential signal. The receiver includes arming circuitry configured to place the receiver in an armed or unarmed state based on the voltage differential signal, a first threshold corresponding to a first CAN protocol, and a second threshold corresponding to a second CAN protocol. When the receiver is in the unarmed state, a first digital signal indicative of activity on the CAN bus is provided based on a comparison between the voltage differential signal and the first threshold, and when in the armed state, the first digital signal is provided based on comparisons between the voltage differential signal and each of the first and the second thresholds.

Abstract: The disclosure relates to a controller area network, CAN, unit and associated method and computer program. The CAN unit is configured to detect a transmit signal edge on a transmit signal for a CAN transceiver; detect a corresponding receive signal edge on a receive signal for a CAN controller of the CAN transceiver; and detect a collision on the CAN bus based on a propagation delay between the transmit signal edge and the corresponding receive signal edge.

Abstract: Various aspects are directed to communications, as may be implemented in an automotive network. An input transistor has a gate coupled to an input port and to a voltage-limiting circuit, connected between the gate and a power rail. The voltage-limiting circuit presents a voltage to the gate corresponding to a voltage on the input port and less than the supply voltage level, and clamps a gate-source voltage of the transistor. In a power-saving mode, current is blocked on the current path when the input port is at the supply or ground voltage levels. When the input port transitions away from the threshold voltage, the apparatus transitions to a wake-up mode in which current is no longer blocked in the current path and in which a wake-up signal is provided based on the voltage at the input port and a bias voltage.

Abstract: Various aspects of the disclosure are directed to methods and apparatuses involving communications. As consistent with one or more embodiments, first and second sets of multiple current drivers are implemented respectively in a high-side and a low-side circuit. Current is driven via an output port in the high-side circuit by activating the first set of multiple current drivers until a steady-state high voltage is detected, and by deactivating one of the current drivers in the first set when the steady-state high voltage is detected. Current is driven in the low-side circuit by activating the second set of multiple current drivers until a steady-state low voltage is detected, and by deactivating one of the current drivers in the second set when the steady-state low voltage is detected.
