I ran into similar issues with a 1:7 (Channel-Link) receiver design. What I did was to use a 1:4 deserializer on each data channel and capture the 1x clock (in your case the FCO output) with a similar deserializer. Then using the value on the clock (FCO) deserializer I used a simple state machine to frame and compose the 7-bit (12-bit) input data word. HTH, Gabor
