Accessing the register block of DP83620

Other Parts Discussed in Thread: DP83620, LM5070

Hello TI,

I would like to know, what has to be done once the circuit has been made ,so as to initialize the DP83620 IC. Do we need to set the register blocks as per the requirement? If yes, how to carry out that via software. I read that there are some strapping options.

How to go about with this? I want to start with the testing phase and for that,I need the PHY IC registers to be set.

I also read that register is accessed via MDIO/MDC interface. I would like to know how to do it? please provide,if there any PDFs.

please help.

Thank you in advance.

For most applications, configuration via the straps is sufficient for normal operation. Are you using the DP83620 EVM or a design of your own creation?

On the DP83620 Tools & software tab (www.ti.com/.../toolssoftware) is a link to the USB to MDIO Serial Management Tool. This GUI can be used with an MSP430 LaunchPad to access the registers via MDC and MDIO.

thanks Patrick.. I am trying to use evm board as reference and making my own design. If its my own design,then I wont be able to use the software? what if, I write some driver code segments,will that help?
and in the reference schematics that are provided on site, those values of the components are fixed? or some amount of variations are allowed?

Also, I am trying to add PoE circuitry to it using LM5070. what all things I need to take care about while designing?

sorry for the trouble, but do reply. Thanks in advance.
