DP83822HF: reference design with SFP

Xianrong Shang

Part Number: DP83822HF
Other Parts Discussed in Thread: TIDA-00928, DP83822EVM, USB-2-MDIO

I find there's no SFP in the TIDA-00928's sch.

Can SFP replace directly the AFBR-5803Z ? what's the difference between AFBR-5803z and SFP ? Do you have any reference design with the SFP ?

Hi Xianrong,

If you are looking for reference material on how to connect SFP module to DP83822, you can use the DP83822EVM schematics. The schematics are here: www.ti.com/.../snlu179.pdf
The EVM uses a SFP instead of AFBR-5803z. The AFBR-5803z is a different type of Fiber Optic module.

Hello Aniruddha,

Which ARM platform should the DEMO board DP83822EVM be in ? can you recommend micro-processor 's P/N?

and can you provide the driver program which has the MAC, PHY , MDIO interface?

The DP83822EVM has a header that a MAC can be wired to. There is no processor on the EVM.
You can use USB-2-MDIO tool for communication with the PHY: www.ti.com/.../USB-2-MDIO
