Notes to
(1) For the frequency, data rate, and interface width supported, refer to
(2) This allows the fabric-to-transceiver interface to run below the maximum interface frequency. For more information, refer to
(3) The word aligner uses bit-slip mode. However, this block is not useful because word alignment and framing occurs after de-scrambling. Altera

In HD-SDI mode, the transmitter is purely a parallel-to-serial converter. SDI
transmitter functions, such as scrambling and cyclical redundancy check (CRC) code
generation, must be implemented in the FPGA logic array. Similarly, SDI receiver
functions, such as de-scrambling, framing, and CRC checker, must be implemented in
the FPGA logic array.
