DP83825I: DP83825I WoL power consumption with low power modes
Part Number: DP83825I
My customer wants to activate PHY and CPU when a cable is connected.
Customer thinks to let PHY Active Sleep mode
Also, customer thinks to activate CPU by LED0 output because WoL feature couldn't be used..
In this case, what is the state of "Link is good"?
My expectation is that PHY will receive NLP from the link partner, PHY will become active, and after some negotiations, a voltage will be applied to LED0.
Another question related active sleep mode is what is the state of "Active but not Link" in power consumption value in the datasheet?
Is it a situation that 'there is no cable detected but not in active sleep mode' or 'a cable is detected but there is no communication'?
Yes, LED0 "link is good". LED is ON when PHY link-s up.
Your proposal looks good to use the PIN for wake-up.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Geet Modi:
Nice to hear your confirmation.
How about the other question, the "Active but not link" ?
In reply to Hideki Hayashi1:
"Active but no link" can be considered as a mode when phy is active and ready to link but :
1. either no cable connected.
2. or link-partner is not active to be linked up.

Thank you for the explanation.
