Overview

...p's PD70211 is an advanced PD interface IC with integrated switching Pulse-Width Modulation (PWM) regulator control for powered devices in PoE applications.
It supports IEEE® 802.
3af, IEEE 802at, HDBaseT, and general 2/4-pair configurations.
The PD70211 front-end includes an advanced classification block that supports 2, 3, 4, and 6 event classification.
Using the SUPP_Sx pins, it also identifies the four pairs of cable that actually receive power and generate appropriate flags.
The IC features an internal bleeder for discharging the input capacitor of the DC/DC converter rapidly to ensure fast re-detection and port power-up, in case of a sudden removal and re-insertion of the Ethernet cable...
