I am trying to implement a BCDR on a Kintex-7 FPGA following XAPP1083. The module of this application note takes as input a 80-bit deserialized data, and I wonder how can be done with the FPGA IO resources since, as far as I know, ISERDES are only up to 8b.
Thanks in advance for your support.

Hi @oli669 ,
XAPP1083 is meant to work with the GTX serial transceivers available in Kintex-7 and not with the ISERDES of the SelectIO.
The serial data stream is oversampled with 12.44Gbps. You will not achieve that with a SelectIO. With -3 speedgrade and FF packages the GTX can run at this speed and it then can give you a data width of 80 bit.

you can have a look at this.
