Hi Kallikuppa Sreenivasa 

After discuss with customer

They need  chip must support 4-core POE, 

DP83TG720S-Q1 seem unmet spec , could you please help suggest a new solution ,THX

Hello  Kygo Cheng

Thank you for the input.

When you mean 4-core did you mean GBE with four pairs?

Hi Kallikuppa Sreenivasa 

YES!

Detail like this,THX

Hello  Kygo Cheng

Thank you for the inputs. 

I am not able to understand the block diagram.

If you are looking for GBE solutions we have the DP83867 for copper only and DP83869 for copper or fiber.

Hi Kallikuppa Sreenivasa 

Thank you

1. If the part of the Ethernet port, customer needs to configure the POE mode, whether there is a related reference SCH?

2.There is a deference for the pin sequence defined in Figure A/Figure B below. Which one should correct?

,

3.As shown on page P115 below, it is mentioned that the DC Blocking capacitor is a 1% accuracy material. Is the requirement too high? Could 10% be used? (BTW. Serdes Coupling Cap. 0.1uf/10%)

Hello  Kygo Cheng

Thank you for the queries.

Let me check and update you early next week.

Hello  Kygo Cheng

We do not have a reference schematics for POE.

Please orient the pins in the same direction and both will look same.

For the tolerance, the 1% is typically for the resistors. Please refer the EVM for more details.
