DP83TC813R-Q1: Media Converter Script

Bardia Bandali

Part Number: DP83TC813R-Q1
Other Parts Discussed in Thread: DP83TC813EVM-MC

Tool/software:

Hi,

Sorry, if the question is silly as I am a newbe in Enet-Phys.

I have embedded a media converter based on DP83TC813EVM-MC in our remote platform. I can confirm that I can access and write to both phy's registers via MDIO. 

Could you please inform me about minimum registers, values, and sequence that are required to program for just media conversion? 

Thanks

    Hi Bardia,

    Can you tell us a bit more about the structure of your media conversion application? The DP83TC813 doesn't have any specific configurations for media conversion, but we recommend that it be initialized with the appropriate script from the SNLA389 application note for best PHY compatibility and electrical performance.

    Best,

    Thanks for your reply Evan,

    Following is a brief diagram.

    The 1G ports of the "embedded M.C." are connected to a switch which itself is connected to local network where an application on a PC will control and take care of the remote loggers and their data. Considering that "embedded M.C." is an exact replica of DP83TC813EVM-MC which its two Phy's RMII are connected back to back, the goal is to convey recevied packets on 100Mb-STP wires to 1G ports without intervention of our "system's CPU" (sounds ok?). 

    Could you please inform which script (or set of registers/values) to use for this application?

    Hi Bardia,

    There is no specific script on the DP83TC813 necessary for media conversion, we recommend just configuring it with the standard initialization script that I mentioned before. The DP83867 <---> DP83TC813 connection is formed automatically and packets can be sent both ways as long as both parts are configured to a matching MAC interface. 

    Best,
