DP83869HM: Schematic Review

Manoj Chate

Part Number: DP83869HM
Other Parts Discussed in Thread: DP83869

Hi Team,

We have used DP83869HM to implement SFP interfaces. Input to DP83869HM is coming from ethernet switch which is from 100Mbps PHY port which ultimately produce SFP data over 20-pin connector.

Also , we are planning to use all these 2 PHYs on single MDIO line , could you please verify the PHY address as well. VDDIO for system is 3.3V

Kindly review and provide your valuable feedback.

Thanks ,

Manoj

Hello Manoj,

Thank you for the mail.

I will review the schematics and provide the feedback before early next week.

In the meantime if there is a block diagram that you can share on the overall connection, that would help.

Regards,

Sreenivasa

Hello Sreenivasa,

Please find the attached block diag. which may be useful during review.

As port sharing is done - only one interface will be implemented at one time.

Thanks

Manoj
