Hi team,

My customer now have designed P2P replacement from 100MHz DP83TC811 to 1000Hz DP83TC720.

The PCB board are the same in 811 and 720.

When go into sleep mode, the power (1.8V3.3V/1V) of 811 are still power up. It can't be cut-off.

Customer want to know whether it is ok for 720 when go into sleep the power rails (1.8V/3.3V/1V) are still on?

If it could, will it impact the power consumption?
