FX3 rise time?

 Hello,

   

 

   

If the trace length is less than 1/6 of the      

 

equivalent length of the rise and fall times, the series termination .is not needed

   

 

   

I need to know if i need impedance matching for the data and control lines. i can't figure out the rise time for the GPIFII from the datasheet

   

 

   

Regards,

   

Assaf
