DP83867E: Interface forum

Part Number: DP83867E

Hi. Team

I am going to apply DP83TG720S-Q1 to my project.
I tried to compose the Ethernet circuit referring to the EV circuit diagram.

I am trying to do 1G Ethernet communication.

I'm asking for advice on whether there are any problems with the schematic I wrote.

1. Check my schematic 
2. I wonder what the power sequence will be like with 3 power input. Should 1.8V be supplied after 2.5V is supplied?
3. Are there any precautions to take when connecting the dp83867 to SERDES1?

thanks

Hi Cho,

We will review the schematic with in 3- 5 business day and get back to you later this week
Yes, 1.8V can come after 2.5V. Please refer to the figure 34 on the datasheet for the timing requirement
Can you explain further on what is SERDES1? where is it in the schematic?

Regards,

Hillman Lin
