hi,
i am willing use lan81c185 with my fpga board and made my first the lan board.i just hook up the oscilloscope to tx_clk line(MII interface).it seems there were some overshoots and other distortions.
i like to know whether i need to hook up a Schmitt triggering ic to condition the clock signal before connecting to the fpga.(please check the attachment)
Thanks a lot!
