DP83867E: Power Consumption with SGMII

Genius 12090 points

Part Number: DP83867E

Customer is going to do the evaluation on power consumption of the DP83867ERGZR.

In the d/s, it is only showing typical value. is there max. power consumption info.?

We found SULA241 application notes, there proving more details about power consumption. however, are they in max.or typical value?

Last question, the power measurement is for RGMII mode, if customer using SGMII mode, are both the same in power consumption?
