Dear Team,
I have a question regarding the power consumption of DP83822H. In the datasheet one can find measured power consumptions @ 25°C:
220mW @ AVD=3V3
120mW @ AVD = 1V8
Unfortunately we do not spec what cable length was used. Did we use max length with 150m? We need to know the expected power consumption for the following use cases to estimate the power supply design:
- 100BaseT @ 100m cable length @ 25°C
- 100BaseT @ 100m cable length @ 85°C
- 100BaseT @ 100m cable length @ 105°C
Where could I obtain more precise data for the expected power consumption over cable length and temperature?
many thanks
Lutz
