6.3.1. Transmitter Blocks
The dedicated circuitry consists of a true differential buffer, a serializer, and fractional PLLs that you can share between the transmitter and receiver. The serializer takes up to 10 bits wide parallel data from the FPGA fabric, clocks it into the load registers, and serializes it using shift registers that are clocked by the fractional PLL before sending the data to the differential buffer. The MSB of the parallel data is transmitted first.
The following figure shows a block diagram of the transmitter. In SDR and DDR modes, the data width is 1 and 2 bits, respectively.
