DP83867CR: DP83867 with indicator light problem

Shuang Feng76

Part Number: DP83867CR

The PHY chip is DP83867, and below is some problems we meet:

1. PHY doesn't work after power on (after plug the Meker burner doesn't light up); Sometimes, it will light after press the reset button (connected to reset_n);

2. Why the interface indicator light doesn't light up after PHY startup and why it needs to be lit up after the network cable is inserted?

3. How to connect MDC and MDIO interface with multi-block PHY;

Hi,

1. Can you share the schematics?

2. Is it the MDI interface you're asking about? The PHY Link LED should only turn on when there is network cable connected to a link partner and the link is established.

3. What is multi-block PHY? Can you provide the block diagram?

Also follow this app note for troubleshooting guide: http://www.ti.com/lit/an/snla246a/snla246a.pdf
