Give Feedback Byte Ordering Register-Transfer Level (RTL)

Intel® Stratix® 10 L-Tile and H-tile devices take advantage of the Standard PCS block to implement sub-10G CPRI and Ethernet protocols.

The maximum clock speed of the FPGA core limits the FIFO interface. In situations where the FIFO clock speed exceeds the FPGA core clock speed specification, the byte serializer block scales the data width (x2 or x4). The following figure demonstrates the behavior when there is a core clock speed violation.
