DP83822IF: Fast link down mode and link loss timer

Genius 17295 points
Part Number: DP83822IF

Hello,

 

My customer has 2 questions about DP83822IF

 

1.

The default value of “Fast Link Down Mode” in CR3 is 0.

They think it is OK to leave it default 0 for usual ethernet communication.

And this mode should be enabled in EtherCAT.

Is this understanding correct?

 

2.

Regarding link loss timer, it is specified 50ms min/150ms max in 10BASE-T in the standard.
Is this value also same as 100BASE-T?

 

Regards,

Oba
