I am using an altlvds_rx mega-function with Arria V. How does the reciever's output data is ordered with respect to the serial input data, MSB/LSB first? meaning, if i use a SERDES factor of 2, ...

Honored ContributorI believe the dedicated LVDS hardware just loads it serially into a FIFO(shift register) and you read it out in parallel, so the first one in is the MSB. In the /2 example, I was just pointing out that 01 and 10 are not the only two possibilities. Even if the first in correlates to the higher order bit, you could still have x0 come out first, then 1x, depending on the data relation to the clock.
