Hello all!

I'm novice in designing of ethernet interface.

I faced with issue, which I couldn't solve with google and datasheets.

How to connect RMII_REFCLK pin to DP83848K?

As far as I understand, I should connect RMII_REFCLK  directly to CLKBUF pin of Blackfin. Also I should connect X1 pin of DP83848K to CLKBUF pin of Blackfin and leave pins TX_CLK and RX_CLK unconnected. Is it true?

Thanks a lot!
