Hi,

I have started working on Ethernet media converter that takes input from ethernet and transmits over optic fiber cable.

I have bought one ethernet media converter that has RTL8201FC and it works well for my application.

i want some suggestion regarding DP83869HM if it will work exactly same as RTL8201 or not? If yes is there any firmware or software requirements for this or just need to complete the circuit like plug n play kind.

if there is any reference schematic please suggest that as well.

Here is the media converter i bought from market

Thanks

Hi Anmol,

We expect DP83869HM to work the same way as RTL8201FC. DP83869HM can be programmed two ways: HW or SW.
For SW method, please do the following writes:

For HW method, the following strap configuration must be done for the pins mentioned in the below table:

Please note that 10M media conversion is not supported on DP83869.

Best,
