SERIAL PROGRAMMING INTERFACE (SDO)

(1) For subgroup definitions, please see Table 6-1.

(2) t_ADC is an exact, unrounded, deterministic delay. The delay can be negative if the reference sample is sampled after the SYSREF high capture point, in which case the total latency is smaller than the delay given by t_TX.

(3) The values given for t_TX include deterministic and non-deterministic delays. The delay varies over process, temperature, and voltage. JESD204B accounts for these variations when operating in subclass-1 mode in order to achieve deterministic latency. Proper receiver RBD values must be chosen such that the elastic buffer release point does not occur within the invalid region of the local multiframe clock (LMFC) cycle.

(4) t_AJ increases because of additional attenuation on the internal clock path.

(5) This parameter is specified by design and is not tested in production.
