8.4.2.1 JESD204C Transport Layer Data Formats

The ADC core output samples are formatted in a specific fashion for each JMODE setting based on the transport layer settings for that JMODE. The following tables show the specific mapping formats for a single frame for each JMODE. The symbol definitions used in the JMODE tables is provided in Table 8-20. In all mappings the tail bits (T) are 0 (zero). All samples are formatted as MSB first, LSB last.
