Abstract:
In one embodiment, a powered device (PD) (402) has a PHY module (410) and a media access controller (419) (MAC), the PD (402) adapted to connect to power sourcing equipment (PSE) via a cable, (408) where the PD (402) is adapted to communicate with and receive power from the PSE via the cable, in accordance with the Power-over-Ethernet (PoE) standard. The PD (402) extracts (413) from the cable (408) a DC signal used to power the PD without using a transformer. Capacitors (420) located in the signal paths between the MAC (419) and the cable (408) support electrical isolation of the MAC (419).
