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.

摘要： The present invention provides a method to at least partially power an Ethernet device from a plurality of balanced network power signals received through a network connection. This involves attaching the network device to the network, wherein network signals are received and contain both power signals and/or data signals. These network signals may be passed through surge protection and power-conditioning circuitry wherein the output of these circuits may be provided to a power absorbing circuit. This power absorbing circuit may separate the communication signal and power signal from the network signal. The communication signal may be passed to a network physical layer while the power signal may be passed to a power distribution module. Additionally, because certain embodiments may provide multiple pairs of network power signals to the power absorbing circuit, the current or power associated with each power signal must be sensed and balanced. This may be done with an active control circuit. The balanced power signals may then be supplied from the power absorbing circuit to the network-attached device in order to at least partially power the network-attached device.

摘要： A signal isolator comprises an isolation barrier, a transmitter, a differentiator, and a recovery circuit. 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.

摘要： Embodiments of the present invention provide an integrated circuit (IC) having an integrated DC-DC power converter therein. This IC is operable to support the distribution of combined power and data signals in a network environment such as an Ethernet network according to protocols such as the power over Ethernet (PoE) protocol. The IC includes a DC-DC power converter, a power feed circuit, and a network physical layer (PHY) module, wherein the PHY module may contain fine line structures susceptible to damage when exposed to excessive voltages. To prevent or reduce the likelihood of damage to the PHY module from voltages supplied to the DC-DC power converter, a common substrate ground is shared between the IC components.

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.
