Hi,
I don't know where to get a 25mhz crystal. There are some 25mhz
4 pin oscillator in farnell, but they require 5v. I don't know if it will
be ok with 3.3v

All the network cards I have, have a 25Mhz crystal on them. I just got a cheap one from ebuyer for 2 pounds and then used the magnetics and crystal from that.

whats the part code, it might help to determine if it can run at 3.3V also give RS a go for the crystal. Mat

Hi guys,

I have just baught a cheap network card in pc-world 5.95
It has a 25mhz crystal and the magnetics are housed in
a HST-005P GROUP-TEC 0540. If you have any information
that would help please feel free... My plan is to lift
these parts soon. Ideally, I would like to leave the magnetics
and to find the inputs on the board, but it's not so easy

thanks.
