DP83867IS: DP83867 SGMII Output During Reset

KENGO AKIKAWA

Part Number: DP83867IS

Tool/software:

Hi,

I use SGMII to interface between DP83867 and MAC.
Please tell me the drive state of pin SGMII_SOP and pin SGMII_SON when pin RESET_N="L".

(Tri-state? Fixed value output? Undefined value output?....)

Thanks and regards,

Thank you, Mayhew-san.

So it's an undefined output state.

Do you know if the value can change during reset?

Thanks and regards,

Hi Akikawa-san,

I do not expect the value to change during reset, the line will be idle.

Thank you,

Evan
