Part Number: DP83867IS

Hi team,

Could you let me know the minimum T1 requirement of DP83867IS?

In the datasheet, only NOM 200ms is specified.

Hi Itoh-san,

Thank you for pointing this out. I double check it with the team. We normally customer to make sure there is no MDC signal during power up process. MDC signal might disturb the clock signal internally inside the block during power up stage. Customer should make sure to wait for 200ms after the PHY is complete power up.

Hi Itoh,

I check with the team. We don't have more information on the minimum requirement on MDC lines after power up.

If possible, Please do let customer to have a delay around 200ms for MDC lines after the power up.

Sincerely,

Hillman Lin
