do not pay too much attention to the datasheet values, as this can be design dependent. You need to make a test design, apply timing constraints and see if it can meet them, as josyb did. Would the I/O timing improve if you use the reverse edges? Ie, use the rising edge to capture the data and use the falling edge to transmit data? (I don't have access to Quartus right now)
