DP83826I: How to configure Integrated terminations on MDI lines in RMII 100M mode

Narasimha Rao

Part Number: DP83826I

Dear sir,

How to configure integrated terminations on MDI lines in RMII slave 100M mode.

Datasheet specifies only for 10M mode.

Please provide clarifications.

Thanks for your help and support.

Hi Narasimha,

Are you specifically looking for series termination resistors on the MII side (RMII slave as you mentioned) or on the MDI lines side ?

Typically we do not recommend series termination resistors on the MDI side, register 30E is programmed for 10base-Te applications.

Hi Rahul,

We are looking on the MDI lines side.

DP83826I datasheet in Table 9-83, provided information about register configuration for 10M Mode (30E).

Do we have another register for 100M mode also? for MDI lines?

Please provide information. Thanks.

Hi Narasimha,

We do not have any specific registers for the 100M mode as described for 10M.
