DP83867IR: Discrete magnetic use

Part Number: DP83867IR

Tool/software:

Hi,

I plan to use discrete transformers and common chokes to keep costs down.

I found that the common choke in TI reference designs is on the line side(Link-PP LPJG16314A4NL).

But the common choke is usually on PHY side in many other reference design.

Please give me some advice where should I put the common choke.

Regards,

Wei
