I'm trying to use iserdes2 to create 12-bit signal by serial-to-parallel convert. But in ug471, it said only 10 or 14 bit are supported when using two cascaded iserdes2.
My question is whether I can use two iserdes2 to create a 12-bit signal?

This is architecture limitation of target device. You can do serdes cascading . Check this related XAPP it may help you

I'm using 7-series FPGAs and xapp1064 is for spartan6. Actually I found this
But it still doesn't tell why 1 to 12 conversion can't be implemented by two cascaded iserdes.
