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.

Interference suppression module and associated methods

A transceiver has a first interface supplied by a first supply voltage to interface with external devices operating in a first supply domain and a second interface supplied by a second supply voltage and adapted to interface to an external communication bus operating in a second supply domain. The transceiver has a first internal communication link, which is adapted to transfer transmit data generated by an external device operating in the first supply domain, from the first interface to the second interface, and a second internal communication link, which is adapted to transfer transmit data be supplied from the external communication bus operating in the second supply domain from the second interface to the first interface.

Monolithic high-voltage transceiver connected to two different supply voltage domains

A proxy slave in a first LIN partition receives data from a proxy master in the second LIN partition which in turn receives the data from a slave in the second LIN partition. The proxy slave stores the data in a data structure and receives a read request from an originating master in the first LIN partition after the data is stored. The read request comprises a LIN message identifier subscribed to by the slave in the second LIN partition. The proxy slave accesses the data stored in the data structure based on the LIN message identifier in the read request; and sends a LIN response to the originating master with the stored data from the slave in the second LIN partition.

Local interconnect network (LIN) messaging between LIN partitions separated by a backbone communication network

A system for assigning addresses to a plurality of communication nodes coupled via a power line is disclosed. Each of the plurality of communication nodes includes a current sensor. The plurality of communication nodes includes one master communication node and the master communication node is configured to start an auto-addressing process by asking the each of the plurality of communication nodes to sink a preselect amount of current and measure current, through the current sensor, flowing through the powerline under the each of the plurality of communication nodes. A first communication node in the plurality of communication nodes that does not measure any current flowing under the first communication node is assigned a first address.

Auto-addressing of communication nodes

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.

Network communication control apparatus, system and method

Various exemplary aspects are directed to apparatuses and methods involving switches communicatively-coupled on a bus where one or more of the switches operate to block signals from passing through the switch in a first mode, and to pass signals through the switch in a second mode. A logic circuit is responsive to addressing information received in the first mode, by storing and configuring the apparatus with the address information. The logic circuit ignores address information received in the second mode (e.g., does not reconfigure the apparatus with address information received in the second mode).
