Hi Srinivas,

Do you mean PoDL (power over data line)? You should be able to use any of of our single pair T1 devices (DP83TG720 and DP83TC81x ).

Best regards.

Melissa

Hello Melissa,

Thanks for the info. Yes. I meant power over dataline (PoDL).

Will check the datasheet, but a quick question, do the recommended parts directly provide the PoDL or with some additional circuitary.

Thank you.

Hi Srinivas,

Some additional circuitry is required to supply the power over the data lines (circled in red):
