7.4.3.1 JESD204B Output Data Formats

Output data are formatted in a specific optimized fashion for each JMODE setting. When the DDC is not used (decimation = 1) the 12-bit offset binary values are mapped into octets. For the DDC mode, the 16-bit values (15-bit complex data plus 1 overrange bit) are mapped into octets. The following tables show the specific mapping formats for a single frame. In all mappings the tail bits (T) are 0 (zero). In Table 21 to Table 38, the single-channel format samples are defined as Sn, where n is the sample number within the frame. In the dual-channel real output formats (DDC bypass and decimate-by-2), the samples are defined as An and Bn, where An are samples from channel A and Bn are samples from channel B. In the complex output formats (decimate-by-4, decimate-by-8, decimate-by-16), the samples are defined as AIn, AQn, BIn and BQn, where AIn and AQn are the in-phase and quadrature-phase samples of channel A and BIn and BQn are the in-phase and quadrature-phase samples of channel B. All samples are formatted as MSB first, LSB last.
