1 Port PSE PoE PD69101 Controller
TYPICAL 4 PAIR APPLICAT I ON
This typical application Illustrates a master / slave “plug and play” Power over Ethernet solution for 4 pairs (date and
spare Wires) Ethernet port switch or hub.
“POS” and “NEG” signals are connected to the switch RJ45 jack via line transformers.
AF and AT modes of operations are set through AF/AT and current set pins (DGND or DVDD).

.
The SYNC pins are used to synchronize between the PD69101 Master to the PD69101 Slave so that line detection,
classification, power on and power off events are inline with the load.
