PRODUCTION DATA.
Connect a resistor from CLS to VSS to program the classification current according to the IEEE 802.3at standard.
The class power assigned should correspond to the maximum average power drawn by the PD during operation.
Select RCLS according to Table 1. For a high power design, choose class 4 and RCLS = 63.4 Ω.
