8.4.2.5 JESD204B Frame Assembly with Decimation

Table 12 lists the available JESD204B formats and valid ranges for the ADS54J60 when enabling the decimation filter. The ranges are limited by the SERDES line rate and the maximum ADC sample frequency.

Table 13 lists the detailed frame assembly with different decimation options.
