DP83822IF: can't link up with SFP transceiver

Part Number: DP83822IF

Hello,

We have a project with DP83822IF that uses 100BASE-FX mode, we have tested our circuit with SFF and 1x9 transceiver and they worked fine,

When we use the SFP transceiver in the same circuit the DP83822IF can't identify the link up even using diferents SFP transceiver,

Could you help us to find what is causing this specific problem with SFP transceiver?

Regards,

William
