ADVANCE INFORMATION for pre-production products; subject to change without notice.
When operating in dual-channel mode, the data from one channel can be routed to both digital down-converter blocks by using DIG_BIND_A or DIG_BIND_B (see the digital channel binding register). This feature enables down-conversion of two separate captured bands from a single ADC channel. The second ADC can be powered down in this mode by setting PD_ACH or PD_BCH (see the channel power down register).
Additionally, DIG_BIND_A or DIG_BIND_B can be used to provide redundant data to separate digital processors by routing data from one ADC channel to both JESD204C links. Redundant data mode is available for all JMODE modes except for the single-channel modes. Both dual DDC mode and redundant data mode are demonstrated in Figure 19 where the data for ADC channel A is routed to both DDCs and then transmitted to a single processor or two processors (for redundancy).
