    Abstract: Disclosed are a transceiver device (100) and a method for interfacing between at least two different voltage domains (12, 14), namely a first supply voltage domain (12) having a higher first supply voltage and a second supply voltage domain (14) having a lower second supply voltage. The transceiver device (100) has: a first interface (110), which is supplied by the first supply voltage and is adapted to interface to at least one external first digital device (20) operating in the first supply voltage domain (12); a second interface (120), which is supplied by the second supply voltage and is adapted to interface to an external communication bus (24) operating in the second supply voltage domain (14); a first internal communication link (130), which is adapted to transfer transmit data, which can be generated by the external first digital device (20) operating in the first supply voltage domain (12), from the first interface (110) to the second interface (120), and a second internal communication link (170), which is adapted to transfer transmit data, which can be supplied from the external communication bus (24) operating in the second supply voltage domain (14), from the second interface (120) to the first interface (110). The transceiver device (100) may be embodied as a monolithic integrated circuit, which may be implemented in silicon-on-insulator, SOT, technology. The first and the second internal communication link (130, 170) may be based on the principles of one of differential voltage transmission (140, 180) and digital current loop transmission (150, 190).

    Abstract: An interference suppression module for an Ethernet transceiver, the interference suppression module comprising circuitry configured to: receive a receiver output from a receiver module of the Ethernet transceiver, the receiver module configured to output a logic-high when a received voltage signal is higher than a receiver threshold, and output a logic-low when the received voltage signal is lower than the receiver threshold; receive an energy detection output from an energy detection module of the Ethernet transceiver, the energy detection module configured to output a logic-high when the received voltage signal is higher than a positive energy detection threshold or lower than a negative energy detection threshold, and output a logic-low when the received voltage signal is between the positive and negative energy detection thresholds; and output a predefined logic state to a receive pin of the Ethernet transceiver when the energy detection output is a logic-low.

    Abstract: Aspects of the present disclosure are directed to single-wire bus communications. In accordance with one or more embodiments, a pull-up current is delimited when a single-wire bus circuit is operated at a dominant level during the transmission of data on the single-wire bus circuit. This approach can be implemented to facilitate power savings, such as in applications involving a master control circuit that transmits signals by driving the single-wire bus circuit between dominant and recessive levels.

    Abstract: A method of operating a plurality of communications nodes in a 10BASE-T1S Ethernet network. The plurality of communications nodes are configured to implement a physical layer collision avoidance, PLCA, process. At least two of the communications nodes are candidate beacon generators. The method comprises: for each of the at least two candidate beacon generators, determining a time delay since a last received beacon, comparing the determined time delay with a threshold value associated with the candidate beacon generator, and if the time delay exceeds the threshold value then setting that candidate beacon generator as an in-use beacon generator; and the in-use beacon generator transmitting a beacon to define the start of a PLCA cycle, thereby triggering a transmit opportunity for each of the other communication nodes.
