Hello!

We use a DP83822I for fiber connection.

SFP module is: SFP-WDM3.03

To registers we send:

0x00, 0x8000
0x00, 0x2000
0x0a, 0x4000
0x17, 0x128

Link is not established

What do we need to do to establish link?

Thank you!

Hi,

Above sequence looks ok, after last command, write below as well to reset the phy:

0x001F, 0x4000

Kindly share your schematics and HW Strapping information incase it does not work.

Regards,
Geet
