Hi,

Thanks for your answer and sorry for replying late.

I feed the altlvds_rx with a 310MHz clock / deserialization factor x10.

Even with a desialization factor of x2 I still have an error: "... location xx does not support I/O registers".

Is there any way to force the compability of this dedicated clock pin with the IO registers function which is required by allvds_rx ?
