    摘要: A power over Ethernet (PoE) system has a reclassification functionality. The illustrative PoE system comprises a powered device (PD) and a power sourcing equipment (PSE) communicatively coupled to the PD. A classification identification component coupled to the PD encodes a classification value. A classification identification component can typically be implemented as a classification resistor, although any other suitable component such as a capacitor, inductor, register, or other structure or method can otherwise be implemented. The PoE system can further comprise a reclassification register in a non-volatile memory that stores a value indicative of a new classification state and a new classification identifier and a power switch that powers the powered device to a classification voltage. A PD controller is coupled to the powered device that reads the value indicative of the new classification state and, if the new classification state is asserted, reads the new classification identifier and sets classification according to the new classification identifier. If the new classification state is not asserted, the PD controller sets classification according to the classification identification component.

    摘要: An interface between two or more integrated circuit devices employs isolation techniques to provide electrical isolation of a digital signal for transmission of the digital signal between a master device and one or more slave devices. Unidirectional isolator channels are utilized to transmit bidirectional digital signals, and a selection of an isolator channel operating in an intended direction is performed by direction control logic. Logic that monitors read and write transactions operates to determine a desired direction of the digital signal and accordingly directs the digital signal through an appropriate isolator channel.

    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: 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.
