Hi All

I have some questions. please help me check the schematic, I'm not sure the DP8322 wiring is correct to connect to the SFP.

1. 0.1uF DC blocking caps is a must between the SFP ?

2. pin 24 is need connect to the SFP LOS.

Thank you.?

Hi Lawrence,

I am having trouble reading the connections on your diagram due to the image quality.

Please use out DP83822EVM with the SFP as reference for the connection.

Thanks,

Cecilia
