Hi All,
I have a doubt about how to connect the P1.15/ENET_REF_CLK pin of my LPC1758 microcontroller with the DP83848 PHY chip.
The Keil MCB1700 demo board use the 50MHz PHY ocillator output to supply the ethernet clock reference but the DP83848 has a specific output to supply this signal (25MHz_OUT, pin 25). This output generates a 50MHz clock reference if operates in RMII mode.
In a future I want to buy the RL-ARM library and I don't want to have problems if I connect the ethernet reference clock to the 25MHz_OUT of the PHY chip.
Someone knows if is correct to connect the ethernet clock reference to this pin of the PHY?
Thanks!!
