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： 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 interface between USB devices employs isolation techniques to provide electrical isolation of a USB signal for transmission of the USB signal between the devices. Unidirectional isolator channels are utilized to transmit the USB signals, and a selection of an isolator channel operating in an intended direction is performed by either direction control logic or a USB hub function. Logic may be employed to detect a device attempting to initiate a USB signal. The logic operates to enable a transmitter on a receiving side and isolate the USB signal through an isolator channel operating in a transmission direction.

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.
