Hello,

Is it possible to set "enabling Auto-negotiation" and " disabling 1000BASE"?

Best regards,

Hi Katsu,

Yes, you can set the DP83867IS to not advertise 1000Base-T capability by setting register 0x0009[9:8] = 0. This way the PHY will not auto-negotiate to 1000Base-T.

Regards,
Justin

Hello,

I have received one more question.

Above situation as device is limited to use for 10/100BASE, can the DB83867IS connect to Pulse trans (H2019NL)?

Best regards,

Katsu

Hello Katsu,

Yes, if you are only operating in 10/100 modes, you can leave channels C & D of the PHY disconnected.
