Part Number: DP83867IR
Other Parts Discussed in Thread: DP83869

Tool/software:

Why are two parts for same function is being used in AM6442x eval board.

MII to MDI conversion is being done in one instance by part- DP83867IRRGZT and in other two instances by DP83869HMRGZT.

Can we go ahead with DP83867IRRGZT only for CPSW and PRU-ISSG network interface.

Hi Umesh,

Yes, if 1000Base-T is your desire, with RGMII or SGMII as the MAC interface, you can go ahead with the DP83867.

The DP83869 would be needed if you wanted to use Fiber (100Base-FX & 1000Base-X).

Alvaro

Hi Umesh,

An external SFP Module is only needed for Fiber Applications, hence the RJ-45 would not be used. Please refer to the https://www.ti.com/tool/DP83869EVM for more information.
