摘要： An open collector/open drain interface, such as I2C interface between two or more integrated circuit devices, employs isolation techniques to provide electrical isolation of a digital signal for transmission of the signal between the devices. Uni-directional isolator channels are utilized to transmit bidirectional digital signals, and a selection of an isolator channel operating in an intended transmission direction is performed by direction control logic. Edge detection logic is utilized to determine changes in edges of a digital signal, thus determining a transmitting device and a transmission direction. The direction state is held in a direction state register. This state is held until the appropriate edge is detected on the transmit side, returning the isolator to the idle state. In the idle state neither side of the isolator is in a driven state. During transmission, the digital signal is transmitted through an isolator channel and sent to a receiving device.

摘要： Embodiments of the present invention provide a power feed circuit operable to supply an Ethernet power signal to a coupled Ethernet network. This power feed circuit includes a number of input nodes, differential transistor pairs, active control circuits and output nodes. The input nodes receive a first power signal such as that provided by an isolated 48 volt power supply. Each transistor of the differential transistor pairs couples to one input node. These differential transistor pairs produce a second power signal which may be supplied to the Ethernet network. The active control circuits sense the second power signal passed by each transistor and are operable to apply a feedback signal to the differential transistor pairs based on the sensed power signal. At least one twisted pair couples to each differential transistor pair's output node and is operable to pass the Ethernet power signal.

摘要： Embodiments of the present invention provide a network device operable to receive a network signal that may include both power and data from a coupled network. This network device includes a network connector and an integrated circuit. The network connector physically couples the network device to the network. An optional protection circuit may provide surge protection or incoming network signals received by the network device through the network connector. An optional switching/rectifying circuit sees the output of the protection circuit and is operable to rectify a power signal when contained within the network signal. The integrated circuit further includes a power feed circuit conductively coupled to the protection circuit and the rectifying circuit. This power feed circuit is operable to separate and pass the received data signal to a network physical layer and separate and pass the received power signal to a power management module. The power management module electrically couples to the integrated circuit but is not necessarily part of the integrated circuit. The power management module is operable to at least partially power the network device for specific circuits within the network device from the received power signal.

The transmitter is coupled to a first side of the isolation barrier and is configured to receive and convert an information signal to a differential signal that encodes information in the information signal in a single transition edge. The differentiator is coupled to a second side that is isolated from the first side of the isolation harrier and differentiates the differential signal. The recovery circuit is coupled to the differentiator and operates to recover an output information signal based on the information in the single transition edge.
