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： In an electronic system, a frequency modulator manages clock signals for electromagnetic interference (EMI) reduction. The illustrative frequency modulator comprises a core oscillator, and a clock divider coupled to the core oscillator that modulates frequency of the core oscillator and deterministically spreads clock spectral components of a digital clock signal whereby electromagnetic interference (EMI) is reduced. The frequency modulator further comprises a circuit coupled to the clock divider that receives the digital clock signal, combines the digital clock signal with a data bitstream for transmission across an isolation barrier, and resynchronizes to the digital clock signal.
