1.6.1.7.2. Data Bit and Content Mapping Scheme

One major function of the transport layer is to arrange the data bits in a specific way between the Avalon-ST interface and the DLL in the JESD204B IP core.
The following figure shows the mapping scheme in the transport layer across various TX to RX interfaces for a specific system configuration.
