TLK3138 MDIO-Interface

Guenter Knittel
Prodigy 100 points

Hi,

I want to use the dual-XAUI transceiver TLK3138, and would like to know how to handle the dual-MDIO-interface.

- What is the purpose of providing two MDIO interfaces?

- Can I permanently disable any one interface and control the entire chip through the other?

- How do I connect VDDM[1:0]?

Thanks
