6.4.1.4. Deserializer
You can statically set the deserialization factor to x3, x4, x5, x6, x7, x8, x9, or x10 by using the Quartus® Prime software. You can bypass the deserializer in the Quartus® Prime IP Catalog to support DDR (x2) or SDR (x1) operations, as shown in the following figure.
The IOE contains two data input registers that can operate in DDR or SDR mode. In DDR mode, rx_inclock clocks the IOE register. In SDR mode, data is directly passed through the IOE. In SDR and DDR modes, the data width from the IOE is 1 and 2 bits, respectively.
You cannot use the DPA and data realignment circuit when you bypass the deserializer.
