The data will be 6 bits per rising edge of the outclock, so SDR. It's independent of the I/O standard, so even if you make the inputs LVDS, it will still be SDR format into the fabric.

I think you are right.. so basically the ALTLVDS_RX does the job of ALTDDIO and shift register and bit allignment?
